Difference between globe and maps
Types and features of maps
Symbols used in maps
Let’s Recall
Pihu: “I found an old box in my grandfather’s room. It had a compass in it. The compass showed the north, but the marks for the other directions were worn off. Help me mark the other directions.”
Aayu: “I am trying to read this map. Help me!”
Fill in the blanks:
1. The hospital is to the __________ (west/east) of the house.
2. The house is to the __________ (north/west) of the school.
3. There are _______ (2/5) trees to the west of my school.
4. The school is to the ______ (south-west/ north-west) of the shop and the school is to the _________ (south/south-east) of the hospital' to 'The school is to the _________ (south-west/ north-west) of the shop and to the (south/southeast) of the hospital.
Pihu is visiting her uncles during Diwali. One of her uncles is in Abu Dhabi, while the other stays in Jaipur. She needs to plan her trip. But before that, her father asked her to find these places on the globe or on a map.
The globe does look like the Earth. It is tilted as well. But the places are not too clear. Maybe Pihu could have used a larger and more detailed globe?
On the other hand, the map gives us more detail. In the given map above, we can see Jaipur as well as Abu Dhabi. Important cities are highlighted in the map. Jaipur is the capital of Rajasthan, a state in India.Abu Dhabi is the capital of a country called the United Arab Emirates.
Earlier, people used to think that Earth was flat. They believed that if we reach the far edge of the Earth, then we might fall off the edges.
Ferdinand Magellan, a Portuguese explorer, sailed around the world and proved that the Earth is round like a ball. It is a three-dimensional shape called a “sphere.”
The Earth’s round shape has been confirmed through scientific observations and evidence, such as the way the Earth casts a round shadow on the moon during a lunar eclipse and images taken from space.
Astronomers believe that the Earth is spherical and is slightly flattened at the top and the bottom (like an orange). This shape is called an oblate spheroid or a geoid.
An Oblate Spheroid
The globe is a simple and accurate model of the Earth.
A globe is a very useful tool for studying geography because it shows the Earth’s actual shape and how places are located in relation to each other. It helps us understand the size, location, and features of different countries, continents, oceans, and more. It is mounted on an axis stand.
Explorer: A person who travels to find out about the Earth and people
Model: A three-dimensional representation of a thing or of a structure, usually smaller than the original
Sphere: A perfectly round three-dimensional object, like a ball, where every point on its surface is the same distance from the centre.
Globe: A model of the Earth
The axis is an imaginary line that goes through the Earth from the North Pole to the South Pole. It allows the globe to rotate, just like the Earth spins on its axis. The tilt of the axis is the same as the earth’s actual tilt. This rotation helps you turn the globe and look at different parts of the world. The axis stand also allows you to tilt the globe to see how the Earth is positioned in relation to the Sun, which helps explain day and night and the changing seasons.
Advantages of using a globe
1. We can see the correct shape, size and location of the continents and oceans on the globe.
Disadvantages of using a globe
1. It is small.
2. We cannot see all the details clearly.
3. Difficult to carry.
4. It does not show the entire Earth at the same time.

Pihu’s father told her that maps are representations of the earth’s surface or a part of it on a flat surface like paper or fabric. It shows specific areas clearly. Maps present information about the world in a simple, visual way. It is easy to carry.
It is 3-dimensional.
It represents the entire Earth and cannot be made for just a part of the Earth.
It is difficult to carry around.
It is 2-dimensional.
It can represent the whole Earth or any place like a country or a city.
It can be carried around conveniently. It provides a more accurate representation of the Earth but cannot display additional details.
It can show more details and information than the globe.
There are a variety of maps for different purposes, such as physical maps, political maps, topographic maps, road maps, and many more. You can select the appropriate map according to your needs.
These maps show the boundaries of countries, states, cities, and other political divisions. They are often used to understand the administrative and political divisions of a region.
Physical maps depict the physical features of an area, such as mountains, rivers, lakes, deserts, and other natural landmarks. These maps help students understand the geography of a region.
Thematic maps are designed to convey specific information about a particular theme or topic, such as population growth, migration patterns, or economic indicators.
Thematic Map of India: Annual
The features of the map make it easier for us to understand it better. Let us look at these one by one.
Directions
There are four cardinal (main) directions and four ordinal directions. The main directions are North, South, East and West.
Ordinal directions refer to the direction found at the point equally between each cardinal direction. Ordinal directions are: northeast (NE), southeast (SE), southwest (SW), and northwest (NW).
Maps usually place north at the top and indicate it with an “N.” From there, the other directions—east, south, and west—can be determined.
Scale
It shows how distances on a map relate to real-world distances. For instance, if the scale is 1 cm: 1 km, then 1 cm on the map represents 1 km in reality. So, if two places are 2 cm apart on a map with this scale, the actual distance between them is 2 km.
Colour
Colour is often used on maps to represent different features or characteristics. For instance, blue might symbolise water bodies like rivers or lakes, while green could stand for forests or vegetation. These colours help distinguish and identify various elements on the map more easily.
Word Zone
Map: A symbolic representation of selected characteristics of a place, usually drawn on a flat surface
Signs and Symbols
Signs, symbols, and colours are used on the map to represent various features, such as rivers, mountains, roads, and cities.
Map Symbols
Symbol: Something used for or regarded as representing something else Word Zone
Cartography is the art of making maps, and those who make maps are called cartographers.
Early mapmakers added fake names to catch anyone copying their maps. Long ago, cave dwellers created simple maps to show where they hunted.

The lunar south pole is the southernmost point on the Moon. It is of interest to scientists because of the occurrence of water ice in permanently shadowed areas around it.
While using Google Maps, encourage the child to spot important landmarks and correlate distance to time with them by asking questions. Engage with your child by showing them your city and your relatives’ house on Google Earth. By zooming in and zooming out of the same, encourage the child to look for familiar places in it, like spotting their school/ a park/ a railway station, etc.

Riya and Rahul are going for a movie:
Let’s not be late for the movie. Otherwise, we might have trouble finding a seat.
Our seat numbers are E4 and E5.
Now, answer the following questions:
1. Are they sitting in the same row?
2. In the theatre, Riya sees her cousin watching the same movie. Her seat number is C2. How many rows ahead of Riya is she sitting?
3. Is Riya’s cousin sitting closer to the aisle than Riya and her friend?
4. Is “8” a valid seat number? Why?
5. Is “A” a valid seat number? Why?
We need two pieces of information to reach the correct seat number. Similarly, when we need to find the exact location of a place on Earth, we will need two types of information. What could these be? How can those help us reach the exact location? Let’s find out.
Resham and her friend are studying the globe. They see some lines drawn on it. They are wondering what could those be. What do you think these lines are? Are these actually drawn on Earth or imaginary lines?
Horizontal and Vertical Lines on the Globe
The globe is a model of Earth. It shows some lines on it. These lines are not drawn on Earth — they are imaginary lines. These lines are important for locating places on the map or globe. The horizontal lines are called latitudes and the vertical lines are called longitudes.
Latitudes are imaginary lines that run horizontally around Earth from east to west. They are like a set of circles that help us locate places on Earth’s surface.
The latitude around the middle of Earth is called the Equator. It is at an equal distance from the North Pole and the South Pole. It divides Earth into two halves: the Northern Hemisphere and the Southern Hemisphere.
Word Zone
Hemisphere: One of the two halves of Earth, above or below the Equator
The main features of latitudes are:
1. Latitudes are parallel to each other. The distance between any two latitudes is always equal.
2. They are measured in degrees. They are numbered from 0° to 90° North or South.
3. We start at the middle of the globe, that is 0° (Equator). As we move up, the degree of latitude increases (90° (degrees) at the poles).
4. Latitudes in the Northern Hemisphere are marked as ° N (degree north) and those in the Southern hemisphere are marked as ° S (degree south).
5. All latitudes are complete circles except for poles, which are points.
6. The length of latitudes decreases as we move towards the poles. That means the largest latitude is the Equator.
7. There are a total of 181 latitudes. One is the Equator, 90 in the Northern Hemisphere and 90 in the Southern Hemisphere.
1. Equator: 0 degrees latitude. It’s the starting point for measuring latitudes.
2. Tropic of Cancer: Approximately 23.5 degrees north of the Equator.
3. Tropic of Capricorn: Approximately 23.5 degrees south of the Equator.
4. Arctic Circle: Approximately 66.5 degrees north of the Equator.
5. Antarctic Circle: Approximately 66.5 degrees south of the Equator.
Latitudes help us understand the climate of different regions on Earth. For example, places near the Equator are generally warm, while those near the poles are colder.
One degree of latitude equals about 111 kilometres on Earth’s surface.
Let’s Practise - 1
1. Answer the following questions.
a. What is the longest latitude?
b. Name the latitude found at 66.5° North.
c. Name the latitude found at 23.5° South.
d. What is the total number of latitudes?
Longitudes are imaginary lines that run from the North Pole to the South Pole.
The main longitude is called the Prime Meridian, which passes through Greenwich, England. It divides Earth into the Eastern Hemisphere and the Western Hemisphere.
The main features of longitudes are:
1. All longitudes meet at the poles.
2. The distance between two longitudes is minimum at the poles and maximum at the Equator.
3. They are of equal length and are not parallel to each other.
4. They are numbered from 0° to 180° in the Eastern and Western Hemispheres.
5. The longitudes of 180° East and 180° West are the same line. There are 360 longitudes in all.
Time zones
Longitudes help us determine time differences around the world. Each 15° (degrees) of longitude represents a time zone, which is roughly one hour.
Longitudes and Time Difference Between Latitudes and Longitudes
Imaginary horizontal lines running parallel to the Equator
Distance north or south of the Equator is measured in degrees
Imaginary vertical lines running from the North Pole to the South Pole
Distance east or west of the Prime Meridian is measured in degrees Equator (0 degrees latitude)
Run east to west
Help in understanding climates, dividing Earth into temperature zones, and in navigation
Prime Meridian (0 degrees longitude)
Run north to south
Help in determining time differences, and in navigation
Latitudes and longitudes intersect or meet each other, forming a grid pattern or a network of lines. We use this grid system to find the exact position of any place. For this, we need the exact latitude and longitude of that place.
1. Latitude: Find the latitude on the map or globe where the place is located.
2. Longitude: Find the longitude on the map or globe where the place is located.
3. Intersection: The point where the latitude and longitude intersect or meet is the coordinate for that specific place.
Word Zone
Grid: A grid is like a pattern of straight lines that cross over each other, making squares Coordinate: It’s like the address of a point, using numbers or letters to pinpoint a spot.
Now, look at the map and check if the statement give below is correct:
• Delhi has a coordinate of 28.70° N (latitude), and 77.10° E (longitude).
Longitude Map of India
Longitudes have one very important function: they determine the local time in relation to G.M.T. or Greenwich Mean Time, which is referred to as World Time. Countries to the East of the prime meridian are ahead of Greenwich time. The time zone in India is GMT+5:30 (hours).

a. We can locate places on Earth with the help of imaginary lines called _____________ and ________________.
b. The _____________________ passes through the Royal Observatory at Greenwich.
c. The _____________ are imaginary lines that run from the North Pole to the South pole and are equal in length.
• Latitudes and longitudes are imaginary lines.
• Latitudes are horizontal lines that run from east to west.
• Latitudes run parallel to the Equator.
• Longitudes are vertical lines that run from the North Pole to the South Pole of Earth.
• Latitudes and longitudes intersect to make a grid system, which can be used to locate places on the globe or a map.
Imagine you are planning a family vacation and have two options: Country A near the equator and Country B at a higher latitude. How would you predict the climate in each country based on their latitude, and what factors might influence your decision on where to go for a holiday?
Compare the grid system formed by latitudes and longitudes with X-axis and Y- axis. How will you write coordinates to indicate a point on graph paper?
Find out the time zones of some countries and compare them with Indian Standard Time (IST). Based on the location of the country, explain these differences.
The International Date Line (IDL) is an imaginary line of demarcation on the surface of Earth that runs from the North Pole to the South Pole. It lies on the opposite side of the prime meridian. It demarcates the change of one calendar day to the next.
The time difference on either side of this line is 24 hours. So, the date changes as soon as one crosses this line. This line is drawn through where the sea lies and not on land to avoid any confusion of date. Hence, the IDL is drawn in a zig-zag manner.
Encourage your child to find the coordinates of the town/city you live in. Ask them to find the coordinates of other towns/cities, states, and countries.

• Factors affecting the climate of an area
• Climatic conditions in the three heat zones – the Torrid Zone, the Temperate Zone and the Frigid Zone
Observe the given pictures and complete the words to describe the weather.
Imagine you are going on a trek on a high mountain. Write down any three important precautions and safety measures you will take before going on the trek, keeping in mind how breathing would be difficult in high altitudes.
Weather is the condition of the atmosphere at a particular place on a particular day or time. The condition of air, temperature, wind, humidity and rainfall at a particular time determines the weather of that place.
Atmosphere: The layer of air around the Earth
Temperature: The measure of how hot or cold something is
Humidity: The amount of moisture in the air
Weather is a temporary phenomenon because it changes every day. It may even change during the same day. Some days, the weather might be cloudy in the morning, but by afternoon, boom! It is sunny.
How are weather conditions recorded?
A thermometer tells us the temperature and a barometer helps predict changes in the air pressure in an area.
Word Zone
The climate of an area is the sum total of the weather it experiences over a very long period of time, such as years or decades. Unlike the weather of a place, which may keep changing, the climate of a place remains the same year after year.
The climate of an area is not affected by hourly or daily changes in the atmosphere. It is affected by conditions over an entire region rather than one specific area. For example, Mumbai is located on the western coast of India near Arabian Sea. It has tropical wet and dry climate with high humidity. So, most places on the western coast will have a similar climate as Mumbai.
Phenomenon: A remarkable event or happening
Thermometer: An instrument to measure temperature
Barometer: An instrument to measure pressure changes
Decades: Periods of ten years
Refers to the actual atmospheric conditions at a specific time and place
Describes what you experience outside your window on any given day
Can change quickly, even from hour to hour, and is influenced by local conditions, like unexpected rain on a sunny day
Represents the long-term average of weather conditions in a particular area
Describes what the weather is typically like in that place over years or decades
Is more stable and is influenced by regional conditions, like the location of a place near the sea or in the mountains
The Earth’s average temperature has increased by about 2° Fahrenheit (1° Celsius) since the late 1800s. This warming is mainly because of the increased release of carbon dioxide into the air by burning fossil fuels. As recorded till date, the years 2016 and 2023 were the hottest so far.

c. Weather can change rapidly, from sunny to stormy, in a matter of ____________, while climate represents average conditions over __________.
d. Understanding ____________ is important for choosing daily outfits, while understanding ____________ helps in long-term agricultural planning.
Many factors play a crucial role in shaping the climate of a region. Let’s explore them.
1. Distance from the equator
The climate of a place is significantly affected by its distance from the equator. Regions near the equator experience hot climates because the sun’s rays fall directly on them, concentrating the heat in a small area.
Word Zone
Concentrating: Focusing on a smaller area, increasing the strength
As we travel from the equator to the poles, the sun’s slanted rays cover a greater area. This makes the heat less concentrated, resulting in cooler temperatures.
That’s why the north and south poles have an extremely cold climate, whereas equatorial areas have a hotter climate.
Altitude is the measure of the height of a place above sea level. The temperature tends to drop about 1° Celsius for every 100 metres increase in altitude.
Weather Impacted by Altitude
Places at higher altitudes, like hill stations such as Ooty in the Nilgiri Hills, have colder climates compared to lower-altitude areas. Even though Ooty is near the equator, its higher altitude keeps it cool. The Himalayan peaks are much higher than the Nilgiris. They remain snow-covered even during summers.
Oceans heat up and cool down slower than land, resulting in a moderating effect.
During the day, the land heats up faster than the water. As the land becomes warmer, the air above it rises, creating a low-pressure area. Cooler air from the sea moves in to fill this low-pressure area, creating the sea breeze. Sea breezes are common in coastal regions, especially on sunny days. They have a cooling effect on the land, making coastal areas more comfortable during hot afternoons. They also bring moisture from the sea, which can result in cloud formation and sometimes rain.
During the night, the land cools down faster than the water. As the land loses heat, the air above it becomes cooler and denser, creating a high-pressure areawhereas low pressure builds up above the water. Cooler air from the land moves towards the sea to fill this low-pressure area, resulting in the land breeze. Land breezes are common in coastal areas during the evening and night. They have a warming effect on coastal areas during the night.
The movement of the sea and land breeze keeps coastal areas like Mumbai cool in summer and warm in winter compared to other areas of the country. The regions far from the sea have more extreme temperature variations, like the northern parts of India, which experience very hot summers and freezing winters.
Word Zone
Denser: Having more mass or particles in a given volume, making it heavier or more tightly packed
Wind direction plays a role in climate. Sea breezes, which blow from the sea towards the land, bring moisture and rain to coastal areas like Mumbai. Land breezes, blowing from land to sea, are warm and dry.
Humidity is the amount of water vapour in the air. An increase in humidity increases the chances of rainfall. Coastal regions like Mumbai tend to have higher humidity levels as evaporation of surface water in the day increases the amount of water vapour above such areas. In colder places, the increased humidity results in snowfall rather than rainfall.
The air becomes thin at high altitudes and contains much less oxygen. This can cause illnesses in humans, such as altitude sickness. Humans have difficulty breathing above 5,500–6,000 m. The altitude of Mount Everest is 8,848.86 m. Mountaineers train for months and carry oxygen cylinders to climb such high mountains.

1. Give reasons for the following.
a. Places near the equator have hot and humid climates, while those closer to the poles have colder climates.
b. It may rain on a sunny day in coastal areas.
c. The high mountain tops are covered with snow even in summer.
d. The coastal areas have a hot and humid climate.
e. Land breeze is dry and warm.
The climate of the poles is very different from the climate near the equator. All the places in a certain area have similar climatic conditions based on the factors that influence its climate. So, the world is divided into three distinct climatic zones based on regions with similar climatic conditions. These are the Torrid, Temperate, and Frigid zones.
The Torrid Zone
Also known as tropical zone or tropics, this zone lies between the Tropic of Cancer and the Tropic of Capricorn. It receives direct sunlight, resulting in a hot and humid climate. Some parts of this zone also experience heavy rainfall. India lies in this zone.
The Temperate Zone
This zone covers the region from the Tropic of Cancer to the Arctic Circle in the Northern Hemisphere and from the Tropic of Capricorn to the Antarctic Circle in the Southern Hemisphere. In this zone, sunlight falls at an angle, leading to a climate that is neither extremely hot nor very cold.
The Frigid Zone
Also known as polar zone, this zone includes the areas from the Arctic Circle to the North Pole in the Northern Hemisphere and from the Antarctic Circle to the South Pole in the Southern Hemisphere. This zone has extremely cold conditions and remains snow-covered throughout the year.
Word Zone
Humid: Air with lots of moisture Angle: At a tilt or slant
Torrid zone has the largest varieties of plant and animal species due to various factors including consistent climate, abundant sunlight and high rainfall.

Our Earth is not a plain land mass. It has points as high as the Mount Everest and regions as low as the Spiti Valley. From deserts to plains to plateaus, we see a variety of different places on Earth. These variations are called landforms. Landforms are also called relief features.
Aayu and Pihu are studying the globe to understand what it represents. Do you know what the different colours on the globe stand for?
Let’s
Mountains are elevated landforms with steep and sloping sides and peaks.
Some mountains are not very tall. They are known as hills.
When mountains are grouped together, they form a mountain range. Examples of mountain ranges include the Andes and the Himalayas.
Newer mountains, like the Himalayas, have sharp peaks whereas the Aravalli in Rajasthan, being older mountains, have rounded peaks.
Features of Mountains
• Mountains have less vegetation at higher altitudes due to snow cover.
• People usually inhabit the lower parts and foothills of mountains.
• Mountains act as natural barriers against cold and hot winds.
Word Zone
• Rivers originate from snow-capped mountains, supplying water to various areas.
• The slopes of mountains are rich in flora and fauna.
• Mountains are a source of various minerals.
• The scenic beauty of mountains and their surrounding regions attract tourists.
Plateaus rise above their surroundings like mountains and hills, but they have flat tops without peaks, often called tablelands. They are found in all continents.
• The geographic location of the plateau decides the vegetation found there.
• Some plateaus can be hundreds of kilometres long, like the Deccan Plateau in India, which spans over eight Indian states.
• Minerals such as coal, iron ore, bauxite, manganese, and copper are often found in plateaus. Many rivers flow through plateaus.
• Some plateaus have canyons, which are deep valleys with steep sides, usually with a river flowing through it. The Grand Canyon, for example, is located in the Colorado Plateau in the United States of America.
Plains are large, low-altitude landforms formed by rivers. Rivers originate in the mountains and flow down. These rivers deposit sand and silt along their beds, gradually creating plains. These landforms can be found near seas across continents.
The northern plains of India have been formed by rivers Yamuna, Ganges, Brahmaputra and their respective tributaries.
Features of Plains
• Plains have fertile soil from river deposits, making them suitable for agriculture. They support the growth of a wide variety of crops.
• Plains are more populated than mountains and plateaus. Many towns and cities can be found in the plains.
• Many historical civilisations have flourished along riverbanks on the plains.
• Plains are ideal for human settlement due to good transportation, availability of water, and fertile soil.

Deserts are vast sandy areas with minimal rainfall and extreme temperatures. They have very little vegetation, and only a few animals like camels, lizards, and snakes can survive there.
Some of the famous deserts of the world include the Sahara desert in Africa, and the Thar and Arabian deserts in Asia.
Features of Deserts
• Deserts are hot during the day and cold at night.
• Deserts receive very little rainfall, making them extremely dry.
• Sandstorms are common in deserts. Sand dunes are small hills of sand that are formed due to the wind.
• Common desert plants include cacti and date palms.
Flourished: Prospered Word Zone
• Oases, or small pools of water, can be found in deserts. They are usually surrounded by date palm trees. These are fertile areas amidst a desert where water and vegetation are present.
• Deserts are usually found in the western parts of continents. Famous deserts include the Sahara desert in Africa, the Thar desert in Asia, the Great Sandy desert in Australia, and the Patagonian desert in South America.
Rivers are natural waterbodies that flow from higher places to lower places. They originate from mountains and go through different places. Rivers are the primary source of water when there is low/no rainfall, supporting the survival of animals and plants. They also help people in travel and trade. Many cities and towns are built near rivers.
A river passes through three different stages:
A. The Upper or Youthful stage
This is the first stage in which the river flows down rapidly from the mountain, creating valleys, waterfalls, canyons, and rapids.
B. The Mature stage
This is the second stage, and begins in the plains. The river is joined by its tributaries and deposits silt along its course. In this stage, the size of the river widens, and the speed decreases. It thus creates loops or meanders.
This is the final stage. The speed of the river reduces further and it is ready to flow into the sea. Just before entering the sea, it breaks into many streams, called distributaries, forming a delta.
The Sundarbans Delta, and the Nile Delta are some examples of deltas.
Features of Rivers
• Rivers have flowing water that goes from higher to lower places.
• Rivers start as small streams and get larger as they join together.
• Rivers can be narrow or wide, and they have curves.
• Rivers have banks on each side.
• Some rivers form waterfalls.
• Rivers flow into bigger bodies of water, like seas or oceans.
• When rivers flood, they can create flat areas called floodplains.
• Rivers are important for plants, animals, and people. They can be used to generate electricity.
Some famous rivers are the Amazon, the Nile, the Mississippi, the Yangtze, and the Ganges.
Mesopotamia is the oldest civilisation in the world. It developed along the banks of two great rivers, the Euphrates and the Tigris. In the midst of a vast desert, the people of Mesopotamia relied on these rivers to provide them with drinking water, agricultural irrigation, and major transportation routes.

Transport is a big challenge in the DRC as they are still working on better roads and trains. Currently, these mainly connect big towns and cities. Rivers are crucial for reaching interior areas and forests. Air travel is also becoming popular in the country.
Water Transport
Mineral resources are the country’s primary economic source. Despite having rich natural resources and valuable minerals, the country is weak economically. Most of the people- more than 70%, live in extreme poverty. However, there have been some improvements in the last two decades, and the economic conditions in the country are gradually improving.
The DRC is very rich in natural resources. It is the largest producer of cobalt ore in the world. It is also the largest producer of tantalum, a mineral used for manufacturing computers and mobile phones. Thus, mining is the primary industry and one of the major occupations in the DRC.
Other minerals found in the DRC are gold, silver, tin, manganese, iron ore, coal, bauxite, and uranium. Most of the minerals are exported as industries are not well developed.
Agriculture is another major occupation in the DRC. It is the source of income for most of the population. The main crops cultivated here are rice, maize, and cassava. The roots of cassava are ground into flour to make bread. The fertile soil also yields a good amount of cash crops like cotton, tobacco, cocoa, coffee, rubber, and oil palm. The cash crops are grown for export to other countries.
Other industries in the DRC are textile, paper, soap, cement, and petroleum industries.

Aayu was reading about the continent of North America. He learnt that it is a big continent which also includes the largest non-continental island of the world. He also learnt that the island contains the tundra region which has very less vegetation and no trees. He began wondering what kind of animals would be found in the region and decided to find out more about it. Can you help Aayu with this?
The largest non-continental island that Aayu read about is located in the Atlantic Ocean and is known as Greenland . It is located in the northern Atlantic Ocean. People in Greenland also call it ‘Kalaallit Nunaat,’ which means the land of the Greenland people. The capital of Greenland is Nuuk, also known as Godthaab, meaning good hope. It is the largest island that is not a continent. It has its own local government and is self-governed as an autonomous province of Denmark.

Greenland lies in the polar region, which is the area surrounding the North Pole and the South Pole. The northern polar circle is known as the Arctic Circle and the southern polar circle is known as the Antarctic Circle. Since the polar region consists of ice and snow, it is also known as the Frigid Zone. Almost two-thirds of Greenland lies in the Arctic Circle.

As Greenland lies in the Arctic Circle, it has an Arctic climate making it extremely cold throughout the year. Almost 80% of Greenland is covered with a single large and thick ice sheet and hence appears white.
The summer season lasts from late May to August and even into September. Summers are very cold; however, the temperatures are not below freezing point. In summer, the temperatures may be around 70 Celsius in the southwestern coasts while 40 Celsius in the Northern regions. The Sun may not set from the end of May till the end of July. This phenomenon occurs in the Arctic region due to the tilt of the Earth’s axis and is known as the Midnight Sun.
However, in the southern regions, there is a bright and sunny climate during summer, with the possibility of 24-hour days.

The spring and autumn have a very short duration in Greenland. The ice sheet that covers Greenland is about 1500 m thick. As snow falls on the ice sheet, it is compressed to form ice layers. As layers get piled up, the weight and pressure cause a large portion to move outwards towards the sea or ocean. These large masses of ice are known as
Sometimes huge portions of this sheet break away and float in the sea or ocean. These are known as icebergs. Since most of the part of the iceberg is underwater, they are a threat to ships.
The northern part of Greenland is only about 710 km away from the North Pole.
The green lights or Auroras, known as Aurora Borealis occur all year round in Greenland but can be seen from the end of September to April. They cannot be seen in other months due to the midnight sun. They attract a lot of tourists from around the world.

Since most of Greenland has large flat plains which are covered with ice, it has a tundra type of vegetation. Very little vegetation is found there. Tall trees do not grow in Greenland as the portion below the topsoil is frozen. This frozen layer of soil is known as permafrost. Mosses, lichens, grasses and bushes grow here.
Herbs grow in some places in summer. Small shrubs and trees are also found here but the trees show stunted growth. Shrubs that grow here are usually berrybearing. They serve as a source of food for animals.

Aayu began to wonder whether the country of Greenland, covered in snow, could support the existence of plants and animals. Let’s explore more about the flora and fauna in Greenland.
The animals here have thick fur to protect against the cold climate. Some are even domesticated for pulling sledges. Polar bears and reindeers inhabit the region, along with musk oxen, arctic foxes, snow hares, certain rodents, and even lemmings.
Marine animals such as walruses, seals, and whales inhabit the seas and oceans. The Greenlandic sled dogs are used for pulling sledges on ice. In the southern part of the country, some goats, pigs, and sheep are also raised. Greenland is home to various birds, including petrels, puffins, gulls, and the white-tailed eagle.

Umiak and Kayak
Some people also work in mines and oil fields. However, most people have now migrated to towns and cities. Most settlements are found in coastal areas due to the thick ice sheet. In addition to Nuuk, Sisimiut, and Ilulissat are other major cities. The economy of Greenland has long been based on the export of fish and shrimp; fish comprise up to 90% of exports. Animal skins are also exported.
Aayu thought that plants and animals have adapted to the Greenland climate, but how do people in Greenland manage to survive there? Let us find out.
The native people in Greenland are called Inuits or Eskimos. ‘Inuit’ is a common term for people living in the Arctic region in different countries. The Inuits in Greenland were people from North America who traveled here and settled a long time ago. They have adapted to the harsh climatic conditions.
To keep themselves warm, the Inuit people wear clothes made from animal fur and skin in layers. Their clothing consists of a tight double-layered jacket with a hood called Parka, double–layered trousers, mittens and water-tight boots also worn in layers. The clothes and boots are made from caribou or seal skin.
In the northern parts of the country, people build houses from blocks of compressed snow. These are called snow houses or igloos. They are domeshaped to allow snow to slide off. They have a narrow opening at the bottom and a small opening at the top for smoke from the fire to escape. The floor is covered with animal skin or fur to keep warm. Since ice is a bad conductor of heat, it does not allow the heat within to escape, thus keeping it warm inside.
Word Zone
Mittens: Gloves without separate openings for fingers
Comprise: To consist of Export: Send to other countries as part of trade
In summer, they stay in tents called tou pigs built from animal skins. Recently they have started living in wooden houses raised from the ground by a metre using pillars.
Traditionally, the Inuits have lived by fishing and hunting, and gathering roots in summer to fulfil their needs, for hundreds of years. But now, they can purchase goods imported from other countries.
The ice sheet of Greenland is enormous and ranks as the second largest in the world; the ice sheet of Antarctica is the largest.
Import: Source or buy from other countries

Some other crops, such as wheat, barley, rice etc., and some fruits and vegetables are also cultivated.
Only animals that can survive the harsh desert climate are found here. It includes different types of insects, snakes, scorpions, desert rats, etc. The most important animal found in the desert is the camel. It has many unique adaptations: broad padded feet prevent sinking in the sand, hump stores fat for nutrition during food scarcity, long legs to distance themselves from hot sand, and eyelashes and closable nostrils shield against the sand. Special mouth structures enable camels to consume thorny plants. Other animals like the Arabian oryx, Arabian wolf, wild goats, caracal, etc., and birds like falcons, eagles, and vultures are also found in Saudi Arabia.

Let’s Learn
Transport in Saudi Arabia is well developed. Major towns and cities, as well as tourist places and places of pilgrimage, are well connected by a network of roadways, railways, waterways, and even airways. Airways also connect it with other countries. Riyadh, Jeddah and Dammam are major international airports. Jeddah, Ras Tanura and Yanbu are major seaports.
In desert regions, camels are the main means of transport as they can live for many days without food and water and can walk easily on sand. Hence, the camel is often called the ship of the desert, as people use it for transporting goods and food.
Saudi Arabia has deposits of mineral oil or crude oil (petroleum) in large amounts. It is exported to almost all other countries in the world through ships.
The major oil deposits are found in Ghawar and Dhahran. Ghawar is the largest oil field in the world. Many refineries in the country produce petrol, diesel, kerosene, etc. from the extracted crude oil. Petroleum is also known as liquid gold because of its high market value.
The discovery of petroleum transformed Saudi Arabia’s economy and lifestyle. As the world’s second-largest producer of petroleum, after the USA, most of the country’s income comes from exporting it. Agriculture in Saudi Arabia relies on desalinated water to grow crops such as wheat, rice, fruits, and vegetables. Saudi Arabia has also developed industries like petrochemicals, cement, iron, steel, and fertilizers. Small-scale industries like textiles, soap, handicrafts, and leather have flourished. The mining industry is gaining importance, too. Key industrial centres include Jubail and Dammam on the east coast and Yanbu on the west coast.
Originally, the people of Saudi Arabia, known as Bedouins, were nomadic and raised livestock like goats, sheep, horses, and camels. They lived in tents and wore clothes woven from the wool. Their diet consisted of dairy products and certain crops, including dates. Since the discovery of crude oil, lifestyles have changed, with Bedouins now living in villages and city dwellers adopting modern living in houses and skyscrapers. People in Saudi Arabia still wear traditional clothes. Men wear a Thawb and Ghutra, and women wear an Abaya and Shayla. Desalination plants ensure water supply in many places.

Large land masses covered with ice and snow are found near the poles and are known as the Arctic Circle and the Antarctic Circle. Tropical regions, covered with dense vegetation, including trees, shrubs, and other plants, are called tropical rainforests. Regions covered with sand are known as deserts. But have you heard of regions covered with grass? Do you know what they are called? Let’s find out.
Aayu was reading a comic book when he came across a character who was a cowboy. He was fascinated by the character with the hat and riding a horse. This sparked his curiosity, and he wondered if such people really existed and, if so, where. He wanted to know more about them. Can you help him out?
Vast regions covered with tall grasses are known as grasslands. Grasslands are found in tropical as well as temperate regions. Thus, depending on the climate, the vegetation differs. That is why they are categorised as tropical and temperate grasslands. Grasslands in different parts of the world have different names. The table given below lists the names of some of the grasslands.

The grasslands in North America are known as the prairies. The word ‘prairie’ is French for ‘meadow.’ These prairies are vast, fertile plains covered with vegetation consisting of tall grasses. They are mostly flat or gently sloped, and in some Word Zone
Tropical: Very hot and humid Temperate: Climate characterized by mild temperatures Meadow: Field of grass
places, they may be hilly. While trees are not commonly found in this grassland-dominated region, areas near river valleys and low-lying plains do have trees.
The prairies are found in the central region of the continent of North America. They lie between the Rocky Mountains in the west and the deciduous forests in eastern America and from the Chihuahuan Desert in the south to the deciduous forests of Canada in the north. Thus, prairies cover the Great Plains, the lowlands of the USA, Canada and the northern part of Mexico, as well as the wet, hilly region in the east. The tributaries of the Mississippi River in the USA and the tributaries of the Saskatchewan River drain this region.
The prairies lie in the middle of the continent; hence, they have a continental climate. This climate is usually observed in large land masses and is characterized by moderate temperatures and rainfall. There is a significant difference in temperature between summer and winter. Summer temperatures range between 18°C in the north and 28°C in the south. In winter, the temperatures vary from -18°C in the north to 10°C in the south of the prairies.
Rocky Mountains in North America Word Zone
Dominate: Prominent or more noticeable
The prairies lie to the east of Rocky Mountains which block the clouds and much of the rainfall. Thus, the region to the east is known as the rain shadow region. Hence the prairies do not receive a lot of rainfall.
The annual precipitation is moderate. This type of rainfall is very suitable for the growth of grasses. The prairies also experience a warm wind in the winters known as the ‘Chinook’. It blows from the eastern side of the Rocky Mountains. These winds blow at a high speed. Since they are almost 10°C warmer than the temperature during winter, they bring about a rapid temperature rise. This causes the snow to melt and makes the grass available for grazing animals. However, the fast winds can also cause the soil to lose moisture and even soil erosion.
Warm winds similar to the Chinook winds are known by different names in different regions. In the European Alps they are known as Föhn winds, in central Asia as Afganet, and in the Andes region of South America, they are known as Puelche.

The main vegetation that grows in the prairies is grass. Grasses of different heights grow there – tall grass, short grass, and mid-grass or middle grass. Different varieties of these grass types are found there, for example, big bluestem (tall), needle grass (short), porcupine grass (short), and wheatgrass (mid-grass). The grasses in the prairies have very deep roots, which enable them to survive the harsh winter. Trees do not grow in the prairies due to a lack of water. The prairies receive very little rainfall, which cannot support the growth of trees. Also, the winters are cold, and the summers are hot; this type of climate is not ideal for tree growth.
However, in areas near rivers, trees such as willows, poplars, alders, etc., are found.
Since this region is very fertile, it is suitable for agriculture. Also, grains, which are grasses, grow very well in these regions. Hence, crops such as wheat, barley, maize, oats, rye, etc., are grown here. Other crops like cotton, potatoes, soybean, canola, alfalfa, and nutritious grasses are also grown here.
The temperate grasslands are also called the ‘Granaries of the world’ due to the large wheat production.
Rye: A grain used for making flour, bread, etc
Canola: A plant with yellow flowers grown for oil seeds
Alfalfa: A herb type of plant grown for grazing
Many different types of animals are found in the prairie grasslands. Due to the abundance of grasses in the prairies, grazing mammals like prairie dogs, pronghorn antelopes, elks, deer, and bison are present.
Though the bison or the American buffalo was once found in large numbers, its population has significantly reduced due to hunting, and it is now endangered. Insects such as grasshoppers, viceroy and monarch butterflies, and dung beetles are found in large numbers.
Predatory animals like coyotes, mountain lions, and birds such as the grasshopper sparrow, prairie chicken, and prairie falcon are also inhabitants of the prairie grasslands. The population of the prairie chicken has also decreased due to habitat loss.
Prairie dogs are not dogs but rodents; they are herbivorous, burrowing squirrels. Despite this, their warning calls sound like a dog’s bark. Thus, they are named after both their habitat and the warning calls they make.

The prairies are not only rich in vegetation, but they also boast significant natural resources. Major deposits of crude oil, bituminous coal, and natural gas are found in the prairies, with coal being particularly abundant in these regions. Additionally, various minerals such as iron, copper, zinc, and phosphate rocks are also present here.
The major activity in the prairies is farming, which covers most of the land. Since the region is located in advanced countries like the USA and Canada, farming is conducted using scientific cultivation methods. Machines such as tractors and harvesters are employed for farming.
Due to the abundance of grazing lands, livestock rearing is also carried out alongside farming, making it the largest cattle-producing region. The prairies host a significant portion of the sheep population in the USA, and goats and horses are also raised in ranges. Dairy farming is another vital activity in the prairies.
As a result of extensive agriculture and dairy farming, food processing industries thrive in this region. Wool production is also a significant industry, with the highest amount of wool in the USA being produced in the state of Texas.
The grasslands are also utilized for recreational activities such as fishing and wildlife observation.
The original people that inhabited the prairies were the Indigenous Americans. They were hunters and herders. They reared huge herds of grazing animals found there like the bison, pronghorn antelopes, elks and deer. They used the hide of animals to make their clothing and shelters. Their shelters were tents called Tepees. Some even used grass to make shelters. The native plants formed a part of their diet. They lived in harmony with nature.
Indigenous Americans
Now the prairies are inhabited by farmers and ranchers. Farmers primarily grow food crops and cotton. Ranchers own ranches to rear animals – mostly cattle and sheep, and primarily produce meat. Hides are used for making leather. Wool is produced from sheep and goats.
Aayu’s curiosity was finally answered when he learned more about cowboys. He came to know that cowboys are animal herders who take care of cattle in the ranches in North America. They ride a horse and round up the cattle. They also perform many other tasks on the ranch.
Nowadays, much of the prairie land is lost to cultivation and agriculture. Only a very small amount of land remains as the natural prairie region. Fact Zone

Grasslands are important for trapping carbon dioxide, a gas that causes global warming. They do this by using plants, especially grasses, which absorb carbon dioxide during a process called photosynthesis. The carbon gets stored in the soil and roots of the grass. Grasslands help fight climate change by holding onto this carbon.

The images you circled are examples of natural disasters — disasters caused by the forces of nature. Let’s learn more about them.
How do weather forecasters predict a natural disaster?
Many natural occurrences take place around us. While some of these occurrences are remarkable, others can be dangerous. The dangerous occurrences are known as natural disasters.
Natural disasters are natural events that can cause damage to property and loss of life. They can happen anywhere. Some of the natural disasters include floods, droughts, landslides, volcanic eruptions, and earthquakes.
Floods are the most common natural disaster. They occur when there is too much water in an area, either from heavy rainfall, melting snow, or a storm.
Floods can cause damage to property and crops. They can also cause serious health risks, spreading waterborne diseases such as cholera and creating breeding grounds for mosquitoes.
In 2022, floods were caused by heavy rainfall in parts of South Africa. Over 300 people were killed and thousands were displaced. The floods damaged infrastructure, including roads, bridges, and power supply.
Cholera: An infectious disease marked by vomiting, cramps, and diarrhoea Infrastructure: The basic system and facilities such as transport and power supply that enable a country or an organisation work effectively
There are a number of things that you can do to protect yourself from floods. These include:
• Staying away from flooded areas and not crossing flooded roads.
• Evacuating the flooded area early and following the instructions of the emergency personnel, in case of an emergency.
• Moving to a higher ground and avoiding open areas that are flooded.
Fact Zone
One of the biggest floods ever recorded occurred in 1931 in China’s Yangtze River. It affected an area as big as England and caused the loss of millions of lives.
Cyclones are large, spinning storms that form over warm oceans. They cause strong winds, heavy rainfall, and high waves. Cyclones can be really destructive, causing floods, landslides, and damage to buildings near the coast.
Cyclone Freddy was one of the strongest storms ever recorded in the Indian Ocean in 2023. It caused widespread damage and floods in Madagascar. The cyclone killed hundreds of people and displaced thousands. Cyclone

Evacuating: Moving from a place of danger to a safe place
Destructive: Causing damage
There are a number of things that you can do to protect yourself from cyclones. These include:
• Staying away from coastal areas during a cyclone warning.
• Evacuating if instructed to do so by the emergency personnel.
• Securing your home and belongings from damage.
Cyclones spin in different directions depending on where they occur. In the top part of the world (Northern Hemisphere), they spin to the left (counterclockwise). In the bottom part (Southern Hemisphere), they spin to the right (clockwise).
Droughts occur when there is not enough rain for a long time, sometimes for months or even years. Droughts impact farming because crops don’t grow without water, and even animals can’t survive. They can also lead to wildfires and severe water shortages.
In 2023, the Horn of Africa faced its worst drought in a long time. Many people there faced starvation. The drought was caused due to climate change, deforestation, and overgrazing. Drought
Word Zone
Starvation: The state of having no food for a long time
Overgrazing: Too many cows or other animals eating grass in an area
We can prevent droughts by planning ahead and being prepared. Let us look at some ways to prevent droughts:
• Water storage and management: We can save water by not wasting it and using it carefully at home, in our community, and at work. We can build dams and reservoirs to store a lot of water and use it in times of disaster.
• Protecting forest: Trees are like nature’s sponges. They keep the soil wet and control rainfall. So, if we look after the trees in our forests, they can help prevent droughts.
• Drought preparedness: We can make systems and plans for early warnings. These systems can tell us early if a drought might happen so we can store enough water and other items.
• Drought-special crops: Scientists are working on growing crops that can grow with less water. Some examples of these drought-special crops are pearl millets and finger millets, quinoa, lentils, barley, sweet potatoes, and more.
The Atacama Desert in South America is one of the driest places on Earth and has experienced extreme drought conditions lasting for centuries.

Landslide
Landslides, also known as landslips, happen when rocks, soil, and debris slide down a hill. Heavy rainfall, earthquakes, or volcanoes can cause landslides.
Landslides can cause damage to infrastructure, land, and other natural resources. They can even cause loss of lives. Landslides are very common in hilly areas. In India, they often occur during monsoon.
Word Zone
Debris: Scattered pieces of things left after something is destroyed
In 2023, heavy rains in Peru caused landslides that killed about 50 people and impacted approximately 8000 by damaging houses.
We should take some preventive measures during landslides. These include:
• Being aware of landslide-prone areas and avoiding those during heavy rainfall or earthquakes.
• Evacuating immediately if you notice signs of a landslide, such as cracks in the ground or movement of soil.
• Not returning to an area damaged by landslide until it has been declared safe by the authorities.
Did you know that landslides can happen underwater, too? They’re called submarine landslides and can be more dangerous than those on land.
Tsunamis are large and powerful waves made by earthquakes, volcanic eruptions, or underwater landslides. They can travel at a speed of up to 804 kilometres per hour and can cause a lot of flooding and damage when they reach the shore.
The 2004 Indian Ocean tsunami was extremely dangerous. It was caused by a massive earthquake near Sumatra, Indonesia. The waves went all the way across the ocean, even reaching Africa and causing widespread devastation.
Recently, in 2022, a tsunami caused by a volcanic eruption in Tonga caused a widespread damage to the coastal areas of the Pacific Ocean. Over 1500 people were displaced, and the damage it caused cost billions of dollars.
There are a number of things that you can do to protect yourself from tsunamis. These include:
• Moving immediately to a higher ground if you are in a coastal area and feel an earthquake.
• Being aware of tsunami warning signs, such as loud sirens or sudden changes in the ocean.
• Not returning to a coastal area until it has been declared safe by the authorities.

Volcanic eruption
Volcanic eruptions happen when hot, melted rock, ash, and gas come out from the earth’s surface. They can cause damage to property, infrastructure, and the environment. Volcanic eruptions can also cause dangerous diseases and loss of life.
Word Zone
Devastation: Destruction, damage
There are about 1,500 active volcanoes worldwide. However, the number can change due to volcanic activity. Some places, such as Hawaii, have volcanoes that erupt with slow, flowing lava instead of big explosions. People there have learned to live with these gentle giants!
In India, there is one active volcano called Barren Island. It is an island located in the Andaman Sea. It is also the only active volcano in South Asia.
There are a number of things that you can do to protect yourself from volcanic eruptions. These include:
• Staying away from erupting volcanoes and following the instructions of the emergency personnel.
• Being prepared to evacuate if you live near a volcano.
• Protecting yourself from volcanic ash by wearing a mask and glasses.
Volcanic eruptions can cause global climate change.
Earth is constantly moving. Sometimes, when the Earth’s tectonic plates move against each other, it shakes the ground strongly. These sudden, ground-shaking events are called earthquakes. They can cause damage to buildings, infrastructure, lives, and the environment.
Tectonic plates: These plates are pieces of Earth’s outer shell which move very slowly. When they meet, they can cause earthquakes, mountain formation, and volcanic eruptions. Earthquake
In 2023, Iceland had a lot of earthquakes — over 800 in a single day! These earthquakes were caused by a new crack in the ground, a sign that a volcano might become active.
Scientists use a tool called the Richter scale to measure how strong an earthquake is. The stronger the earthquake, the higher its number on the Richter scale.
Another instrument used during earthquakes is a seismograph. It listens to the earth’s movement and records this on paper or electronically by creating a picture called a seismogram.
There are a number of things that you can do to protect yourself during earthquakes. These include:
• Staying away from buildings that are likely to collapse during an earthquake.
• Dropping down on the floor, taking cover under a table or a chair, and holding on to something tightly during an earthquake.
• Being prepared to evacuate if you live in an area prone to earthquakes.
• Not taking lifts in case of an earthquake. Use stairs.

Pollution is the mixing of unwanted and harmful substances in the environment that make it dirty. These harmful substances are known as pollutants. Harmful
gases, wastes, plastics, untreated sewage water, etc., are some pollutants. Mostly, human activities cause pollution, but sometimes there are natural causes too.
Pollution is of four main types:
1. Air pollution
2. Water pollution
3. Soil pollution
4. Noise pollution
Let us learn more about each type of pollution.
Air pollution
When harmful substances get mixed with the air, making it dirty and unsafe, it is called air pollution. These harmful substances may be poisonous gases, smoke, soot, and dust. Air pollution has become common in big cities these days.
Causes
Some common causes of air pollution are:
1. Release of harmful gases from vehicles. Besides harmful gases, vehicles also release soot and fine particles.
2. Burning of fossil fuels like coal, oil, and gas in factories.
Word Zone
Sewage water: Wastewater from homes and factories flowing through sewers
Fossil fuels: Fuels like coal, oil and natural gas formed under the Earth’s surface
Soot: Fine black powder consisting of carbon formed when something is burnt
3. Release of smoke and harmful gases from factories and industries into the air.
4. Burning of garbage, dry leaves, and crop wastes.
5. Natural causes of air pollution are forest fires, volcanic eruptions, and sand storms.
Air pollution affects all living things, including plants and animals, and not just human beings.
1. Air pollution can cause breathing problems.
2. Air pollution can lead to lung diseases like asthma, lung cancer.
3. Due to air pollution, plants cannot get enough nutrients from the environment and they may even die.
Breathing Problems
Word Zone
Asthma: A disease affecting the lungs
Effect on Plants
It is important to prevent air pollution for a healthy environment. Some ways to prevent air pollution include:
1. Walking or cycling over short distances.
2. Using public transportation instead of private vehicles.
3. Treating harmful gases from factories and industries before releasing them.
4. Preventing burning of garbage, dry leaves, crop waste, etc.
5. Reducing the use of electrical appliances and saving electricity.
6. Planting more trees as trees helps reduce carbon dioxide in the air.
7. Reusing and recycling paper and plastic materials.
The level of air pollution is measured in terms of Air Quality Index or AQI. Values of AQI below 100 are considered safe.

When unwanted and harmful substances mix in water sources like rivers, lakes, ponds, seas and oceans, it is called water pollution. Pollutants like harmful chemicals, crude oils, plastics, etc., enter water bodies and contaminate them. Pollution of water can be harmful to aquatic animals as well as human beings.
Let us look at the causes of water pollution.
Contaminate: Make dirty or harmful
Crude oil: Type of liquid fuel that comes out of the ground Word Zone
Water pollution can be caused by various factors like:
1. Releasing untreated sewage or wastewater from homes into the water bodies.
2. Releasing wastewater containing harmful chemicals from factories and industries into water bodies.
3. Accidental spilling of crude oil from ships into seas or oceans.
4. Dumping trash and solid wastes like plastic bags or bottles into water bodies.
5. Bathing, washing clothes, and bathing animals in rivers and lakes.
Water pollution can have many harmful effects on plants and animals living in water. It affects humans as well:
1. Mixing sewage water with sources of drinking water can cause diseases like dysentery, typhoid, cholera, jaundice, etc.
2. Food chain can be impacted as the toxins from water pollution can move from one level to another in the food chain.
3. Oil spilling can lead to the death of many aquatic birds and animals.
4. Dumping plastic waste can harm and even lead to the death of aquatic animals.
Untreated sewage: Sewage which has not been disinfected
Oil Spill: Leakage of crude oil on the surface of a large water body Word Zone
Some ways to prevent water pollution are:
1. Keep the rivers, lakes, and other water bodies clean. Avoid throwing garbage and plastics in the water bodies.
2. Treat sewage to remove harmful matter before releasing it into water bodies.
3. Remove harmful substances from industry and factory wastes before releasing them into water bodies.

2. Fill in the blanks.
a. Dumping of plastics in water bodies can cause death of _________.
b. Mixing of untreated sewage in drinking water sources can cause diseases like ________ and ________.
The contamination of soil with harmful substances is called soil pollution. It is also known as land pollution and occurs when trash and poisonous substances are dumped on the ground.
Let us learn about the causes of soil pollution.
1. Littering and throwing around trash or garbage. When the waste materials break down, they release harmful chemicals which cause soil pollution.
2. Use of too many chemicals like fertilisers, herbicides, and insecticides on crops while farming. These chemicals can harm the soil.
3. Mining of coal and minerals. The wastes left over due to mining activities causes land pollution.
4. Presence of landfills where solid wastes are buried. Poisonous chemicals get released from the landfills which cause soil pollution.
Soil pollution can have severe effects on both the environment and our health. Some of these effects include:
1. Pollutants released during mining can release harmful chemicals into the soil and affect its quality.
2. Factories and industries release harmful chemicals into the soil. These chemicals can harm the soil, the plants and animals in it.
3. Harmful chemicals from landfills can enter groundwater and pollute it.
4. Excessive use of chemical fertilisers and pesticides reduces soil fertility. It also kills the helpful soil organisms. Thus, crop yield is reduced.
5. Chemical pesticides are also absorbed by plants and affect our health when we consume them.
Thus, soil pollution has many harmful effects on the environment and people and needs to be prevented.
Excessive: Too much, more than necessary
Yield: Amount of crops produced
Groundwater: Stores of water below the surface of the land
Mining: Extraction of coal and minerals from under the land’s surface Word Zone
1. Avoid littering or throwing waste around and use dustbins.
2. Try to use less, use again, and recycle more.
3. Reduce the use of chemical fertilisers and pesticides.
4. Use of compost and manures made from plant wastes helps improve soil fertility.
5. Reduce the use of plastics.
6. Plant more trees to help hold fertile soil on the land and keep it healthy.
Pesticides are poisonous chemicals which are known to cause many diseases and disorders. Farmers are more prone to the harmful effects of pesticides. They can cause sore throat, allergy, skin irritation, vomiting, and even death. Consuming plants containing pesticides also causes certain diseases like asthma, leukaemia and other cancers.

Pollution is the mixing of unwanted and harmful substances in the environment that make it dirty.
The harmful substances that pollute the environment are known as pollutants.
Air pollution is caused by the burning of fossil fuels, smoke from factories, industries, vehicles, burning of crop residues and garbage, volcanic eruptions, forest fires, etc.
Air pollution can cause lung diseases like asthma, and even cancer. It can also affect the growth of plants.
Air pollution can be prevented by choosing eco-friendly or public means of transport, preventing the burning of crop residues and garbage, planting more trees and recycling.
Water pollution is caused by the release of harmful substances and untreated wastewater in water bodies, oil spills, bathing and washing clothes, bathing animals in water bodies and plastic wastes entering water bodies.
Water pollution can lead to diseases like typhoid, dysentery, cholera, etc., and even cause the death of marine organisms.
Water pollution can be prevented by treating household sewage and wastewater from factories and industries, preventing bathing, washing clothes and bathing animals in sources of water, avoiding dumping wastes in and around water bodies and reducing the use of plastics.
Soil pollution is caused due to littering, plastics, the use of chemical pesticides and fertilisers, mining activities, and harmful chemicals released in landfills.
Soil pollution can cause the loss of soil fertility, kill useful animals in the soil, reduce crop yield and even affect human health.
Soil pollution can be prevented by avoiding littering, avoiding the use of plastics, reducing or avoiding the use of chemical pesticides and fertilisers, using compost or manures, and planting more trees to improve soil fertility.
Noise pollution is caused by unwanted and loud noise.
Noise pollution is caused by the honking of vehicles, aircrafts, the use of loudspeakers, and the use of machines in factories, industries, and construction sites.
Noise pollution can cause headaches, increased heart rate, diseases like high blood pressure and other stress-related diseases, and can even affect animals.
Noise pollution can be prevented by reducing the use of loudspeakers, limiting the time for construction activities in residential areas, preventing honking near hospitals and schools and planting more trees.

The environment is a complex system that includes everything around us, like the air, the water, the land, and all the living organisms. All plants and animals depend on each other and the environment.
Our actions can deeply impact the environment in the forms of pollution, deforestation and climate change. Even actions like wasting water, paper, and
Pollution: Pollution occurs when harmful substances or contaminants are introduced into the environment Word Zone
Deforestation: Deforestation is the process of cutting down or clearing large areas of forests or trees permanently
food can harm our environment. Many animals and plants have become extinct because of our actions. Protecting and preserving the environment is very important for the well-being of our present and future generations.
We can save our precious environment in many ways. Let’s look at some of them:
1. We can celebrate Van Mahotsav and conduct tree plantation drives in different places.
2. We must avoid plastic bags. We could use cloth or paper bags instead.
3. We must not litter public places. We must throw garbage only inside the dustbins.
4. Keep the water bodies like ponds, lakes, seas and oceans clean.
5. We must switch off lights, fans, and bulbs when not in use to save electricity.
6. Excessive food waste decomposes and results in the production of Methane gas, which harms the environment.
7. Conserve water by promptly fixing leaks, using water-saving appliances and fixtures, and being mindful of water usage in daily activities.
Seventy-eight percent of marine mammals are at risk of accidental deaths, such as getting caught in fishing nets. Plastic bags and other plastic garbage end up in the ocean, killing over 1,000,000 sea animals every year.

b. Celebrating _______________ involves tree plantation drives and raising awareness about the importance of trees.
c. To help conserve energy, it’s important to switch off lights, fans, and bulbs when they are _______________ in use.
Substances or things that cannot be used or are unwanted are called waste. These are classified as biodegradable and non-biodegradable waste.
Types of Waste
This includes food scraps, yard waste (such as leaves and grass clippings), and other biodegradable materials. Microorganisms can easily decompose this type of waste.
Biodegradeable Waste (Leaves)
Biodegradeable Waste (Vegetables)
This includes waste materials that do not decompose easily. Plastics, metals, glass, and certain chemicals fall into this category. Electronic waste, such as batteries and parts of computers, is also non-biodegradable waste.
Non-Biodegradeable Waste
Let us see how much time some of the waste takes to decompose.
Non-biodegradable: Any substance that cannot be decomposed by microorganisms easily Word Zone
Biodegradable: Anything that can be decomposed by the action of microorganisms easily
Paper Towel 2-4 weeks
Banana Peel 2-5 weeks
Newspaper 6 weeks
Cotton Cloth 1-5 months
Cardboard Box 2 months to 3 years
Wool Sock 1-5 years
Disposable Diaper 450 years
Plastic Bag 10-20 years
Aluminum Can 80-200 years
Plastic Bottle 450 years (or more)
Glass Bottle Approximately 1 million years (it's difficult to decompose)
Styrofoam Unknown (takes hundreds to thousands of years)
It is clear from the above table that some substances are practically nonbiodegradable. Hence, their use should be restricted.
Archaeologists have discovered landfills that are thousands of years old! In 500 B.C., the city of Athens in Greece had a very rudimentary type of garbage service. Residents were allowed to put out garbage for collection and disposal, but they had to bring it one mile outside the city walls.
Let’s Practise - 2
1. Write two examples of:
Biodegradable wastes - __________________________________
Non-Biodegradable waste – ______________________________
Disposal of waste is also called waste management. Waste management is the practice of collecting, treating and disposing of waste for the protection of our environment. There are a few ways to dispose of waste.
In some cities, garbage is collected daily and transported to places like dumping grounds. The waste is then dumped and usually levelled before the next dumping takes place. This is, however, a harmful method of waste disposal. This can pollute the nearby water bodies and cause harm to us or the animals and plants in that area.
This is the most common method, where waste is buried in specific areas called landfill sites. Properly managed landfills include measures to prevent groundwater pollution and the release of harmful gases.
In this method, waste is collected in a place and set on fire. This can lead to air pollution and breathing disorders in animals and human beings. Burning waste at high temperatures is called incineration. Hazardous and medical wastes are generally incinerated. This method of disposal can become a source of energy if carried out with proper precautions. Without proper precautions, this method leads to air pollution.
Organic waste like food scraps, yard waste, and certain paper products can be composted. Composting is the process of decomposing these materials into nutrient-rich soil, which can be used in gardening and agriculture.
The amazing Vermont Composting Company uses chickens as part of its composting process. The chickens scratch and turn the compost in the food search, adding chicken manure at the same time. It’s a cost-effective process, too – the chickens find so much food in the compost that they don’t need any feeding!

The three Rs - Reduce, Reuse, Recycle- are important principles to follow when managing waste and conserving resources.
This means using less and being mindful of what we consume. For instance, using reusable water bottles instead of single-use plastic ones, or using both sides
Word Zone
Consume: To use
of paper before throwing it away. When we reduce what we use, we create less waste.
Reusing items means finding new ways to use things instead of throwing them away after one use. For example, donating old clothes or toys instead of throwing them away, or using containers and bags multiple times before getting rid of them.
Recycling is about turning used materials into new things instead of just throwing them away. This includes things like recycling paper, plastic, glass, and metal. Recycling is done in factories or recycling units. When we recycle, we help reduce the amount of waste that ends up in landfills and save resources by using them again.
Recycling 1 ton of paper saves 17 trees and 7,000 gallons (26497.88 litres) of water. Fact Zone
1. Name the following.
a. Using less and being mindful of consumption to create less waste. _____________
b. The principle encourages finding new ways to use items instead of discarding them after a single use._____________
c. The term that describes the process of turning used materials into new products instead of throwing them away._____________
d. The R involves actions like recycling paper, plastic, glass, and metal to reduce landfill waste and save resources._____________
Donate: To give away to people who need Resources: The things and materials we use Word Zone
Human activities have caused land, water, air and noise pollution in our environment.
Therefore, we need to save the environment by taking the right actions like saving water and paper and using cloth bags instead of plastic bags, etc.
Waste can be classified as biodegradable (can be decomposed) and nonbiodegradable (cannot be decomposed) by the actions of microorganisms. These wastes need to be disposed of carefully.
Some methods of waste disposal are dumping, burning, burying in landfill sites and composting.
The principle of 3 Rs is important in saving the environment.
The 3 Rs are – Reduce, Reuse and Recycle.
We have learned what 3Rs are. Now, let's incorporate the 4th R? It is called 'refuse'. Can you refuse the items you don’t need? Make a list of things you don’t need and resolve that you will not buy these. Share this experience with your friends about how you were an environmental warrior!

Throughout history, humans have developed effective ways to travel across land, sea, and air, connecting distant places and cultures. Let’s explore some of the major modes of transport that have transformed the way we move around the world.
Roads have been there for centuries. Earlier, people used roads for walking or riding animals. These roads were made of dirt, gravel, or stones and were narrow and curvy.
As time passed and technology improved, roads got better. In the 1700s and 1800s, people started making paved roads using materials like tarmac or asphalt. These paved roads were stronger, weather resistant, and could handle heavier vehicles like wagons and carriages. The development of automobiles also caused major changes in roadways. Cars needed smoother and wider roads, so governments everywhere started constructing better roads. This made travelling easier and faster. Today, roadways are the most common mode of transport, connecting towns, cities, and villages.
India has one of the world’s highest motorable roads, the Khardung La Pass in Ladakh, reaching an elevation of 5,359 meters (17,582 feet). Fact Zone
Word Zone
Paved: To cover the path with concrete, asphalt, stones, or some other material, mainly to construct a road
Tarmac: Material made by combining tar with sand & crushed rocks used for building roads
Asphalt: A black, sticky substance, often mixed with small stones or sand, that forms a strong surface when it becomes hard
The invention of the steam engine in the 1800s led to the development of railways. Railways offered several advantages over roadways. They were faster and could carry much more cargo. Additionally, trains were more comfortable as they had more seating space.
Railways quickly became the preferred mode of long-distance travel, and they played a vital role in the development of markets and societies around the world.
The development of electric and diesel engines further made trains faster.
The Trans-Siberian Railway in Russia is the longest railway, globally covering about 5,772 miles.
In 1903, the Wright brothers made the first powered airplane flight, changing how we travel. Aeroplanes soon became a reality and made flying across continents and oceans possible.
Airways are a fast and easy mode of travel, connecting the world in ways we couldn’t have imagined just a hundred years ago.
Airways has impacted society greatly by allowing fast and convenient travel to distant places. It has also enabled the growth of international trade and tourism.
Airways also connects people across the globe.
The Indira Gandhi International Airport in Delhi is one of the busiest airports in the world, handling millions of passengers each year.
Centuries ago, people started using boats on rivers and seas, discovering the value of waterways for travel and trade. Over time, better ships and technology emerged. In the 1800s, steam-powered ships made water travel faster. Just like aeroplanes changed the way we fly, these advances transformed waterways. Today, boats and ships connect places globally, just as they did in ancient times, playing a key role in our shared history and facilitating trade, exploration, and connections between people across the world.
Over centuries, specific sea routes have emerged connecting different parts of the world. The Silk Road, for example, was an ancient network of trade routes that linked China with the Mediterranean region to allow the exchange of goods, ideas, and cultures.
The Ancient Silk Road:
The Silk Road was a network of interconnected caravan routes that helped in trade and cultural exchange and strengthen the relations between East and West. It also contributed to the development of languages, religions, and art forms along its routes.
The Modern Silk Road: Today, China has revived the concept of the Silk Road with a new idea called the Silk Road Economic Belt. It wants to connect Asia, Europe, and Africa through trade and infrastructure development.
Other important sea routes, like the Spice Route, also connect Europe with India and Southeast Asia. The Transatlantic Route connects Europe with North America, and the Panama Canal is a shortcut route between the Atlantic and Pacific Oceans.
Sea routes continue to play an important role in global trade and transportation. They are an efficient and cost-effective way to transport goods over long distances.
The Suez Canal, connecting the Mediterranean Sea to the Red Sea, is one of the world’s most crucial waterways. It helps in global trade and shortens shipping routes.
Infrastructure: Structures of a country or city like roads, dams, airports, etc.

From ancient cave paintings to modern social media platforms, human beings have always found ways to communicate, share ideas, and connect with one another.
Communication is the process of exchanging information and ideas between individuals or groups. It can occur through various means, including verbal and nonverbal language, written messages, and electronic communication technologies.
Let’s explore major communication technologies that have transformed how we share information and interact with the world.
Personal communication is the exchange of information and ideas between two or more people through face-to-face talking, sending written messages, or using electronic tools.
Over time, humans have created many ways to communicate, starting with verbal language and written symbols and now using advanced technologies.
The postal service has been a foundation of personal communication for centuries, enabling the delivery of letters, parcels, and documents over long distances. It has connected families and friends across borders and has also been important for businesses and governments.
The postal service has also faced challenges in recent years due to the rise of electronic communication channels, such as email and messaging apps. However, it remains an essential service for many people and businesses, especially those in rural or remote areas.
The invention of the telephone in 1876 made real-time voice communication possible over long distances. Telephones quickly became important for personal and business communication. It connected people instantly with each other.
Telephones have changed a lot over time, from early switchboard phones to modern mobile phones. Either way, they remain the most common way for people to connect over long distances.
The first telephone message ever transmitted was by Alexander Graham Bell in 1876. He said, “Mr. Watson, come here, I want to see you.” This marked the beginning of a new era in communication technology.
The internet arrived in the late 1900s, and changed how we share information and talk with others. Now, it’s an important tool for both personal and professional communication, connecting people all around the world instantly. The internet has made a big difference in how we talk, share things, learn, and interact with the world.
Personal communication is an important part of human existence. It connects us with others, helps us learn about the world and become better individuals.
There are different ways to communicate, like talking with friends, chatting with coworkers, or learning from a teacher. Personal communication is the key to building connections and understanding between people.
Sir Tim Berners-Lee, a British computer scientist, invented the World Wide Web (WWW). He developed the first web browser and server, and the first website (info.cern.ch) went live on August 6, 1991.
The invention of the telegraph in the 1830s transformed long-distance communication. Telegraphs enabled rapid communication between cities and countries, aiding the flow of information and enabling faster decision-making.
Telegraphs were widely used throughout the 1800s and early 1900s, playing a crucial role in military communication, business transactions, and news reporting. However, their use declined with the rise of the telephone and other communication technologies.
Fact Zone
Samuel Morse sent the first telegraph message in 1844, which read, “What hath God wrought!” This marked the beginning of long-distance communication via telegraph.
The fax machine, introduced in the 1960s, helped transfer documents over telephone lines. Faxes were widely used for businesses until the rise of digital technologies.
While faxes have largely been replaced by digital file-sharing methods, such as email, they remain used in certain industries that require secure and verifiable document transmission.
Word Zone
Fax Machine
Transactions: Occasions when someone buys or sells something, or when money is exchanged or the activity of buying or selling something
The invention of email in the 1970s marked a shift from traditional letter writing to electronic communication. Emails transformed personal and professional communication, enabling the rapid exchange of messages, attachments, and ideas.
Email uses the internet to send and receive messages, allowing for instant communication across the globe. It has become an essential tool for personal and professional communication, connecting individuals, businesses, and organisations worldwide.
Means of travel and communication have undergone a remarkable transformation throughout history. From the invention of the wheel to the arrival of the internet, these changes have enabled people to connect, explore, and share information in ways that were once unimaginable.

Newspapers and magazines have long served as primary sources of information, providing news, articles, and stories to a wide audience. They played a crucial role in shaping public opinion, spreading knowledge, and promoting intelligent communication.
Newspaper
Newspapers typically publish on a daily or weekly basis, offering timely updates on current events, sports, business, and other topics, while magazines, often published monthly or weekly, delve into specific areas of interest, such as fashion, cooking, or travel.
The invention of the printing press in the 1400s made it possible to massproduce newspapers and magazines. It led to an increase in the availability of information.
Newspapers and magazines continue to play an important role in informing the public, even though they now face competition from television, the internet, and other media.
The invention of radio in the early 1900s led to a new era of communication, bringing news, entertainment, and music into homes. It made people feel like they were part of a shared experience. It also helped them learn about different cultures. Radio programming evolved over time, from live broadcasts of plays and musical performances to news reports, educational programs, and popular music shows.

Think about a time when you were playing a cricket game in the school. There is an umpire to ensure everyone has a fair and enjoyable time. Similarly, the Indian Government acts like the umpire or the person who ensures that all Indians follow the rules and have a fair and enjoyable time. Consider the leaders and important figures we have in India. Can you write down the names of the leaders shown below?
Why do you think it’s important for people to choose their leaders, and how do leaders help run the country?
India is made up of 28 states and 8 union territories. The constitution of India lays out how the government works both at the national level and in each state to ensure everything runs smoothly. The constitution of India clearly defines the powers of both the central and state governments.
Constitution: A set of rules that outlines how a country is governed Union Territories: Special areas in
The central government takes care of defending the whole country, while each state government looks after the law and order within its borders. Sometimes, the central and state governments work together when there’s a need for collaboration. This way, everyone works together to make sure things are wellmanaged all across the country.
The union government, also known as the central government, plays a crucial role in legislating for the entire country. This government takes care of the whole country and has the power to make important decisions and rules that affect everyone. It also oversees important tasks and policies at the national level. The Union Government’s structure is defined by the Constitution of India. The union government is situated in the capital, New Delhi.
The Lok Sabha is like a big decision-making room in India where important laws and rules for the entire country are created and discussed. It’s often called the House of the People or the Lower House because regular people, through elections, choose members called MPs (Members of Parliament) to represent them.
In the Lok Sabha, MPs gather to talk about and make new laws. They also work on changing old rules if needed. These discussions happen regularly to ensure that the country’s laws stay fair and up-to-date.
Word Zone
Legislate: To make or pass laws
The Speaker, a special person chosen by all the MPs, helps keep everyone organised during these discussions.
Every five years, people in India who are at least 18 years old can vote in general elections. The country is divided into smaller areas called constituencies. The person who gets the most votes in a constituency becomes an MP in the Lok Sabha. The Lok Sabha can have up to 552 MPs, each representing a different part of India.
It’s important to note that the Lok Sabha collaborates with another group called the Rajya Sabha to create laws. They discuss ideas, debate, and vote to ensure that the laws are fair for everyone.
The Rajya Sabha is a permanent group that represents the states and Union Territories in India. It’s an important decision-making body also known as the Council of States or the Upper House.
Unlike the Lok Sabha, the people in the Rajya Sabha aren’t directly elected by everyone. Instead, they are chosen by the people we elect in our states. These members represent the wisdom and experience of each state.
The Rajya Sabha is more stable than the Lok Sabha. Its members serve for six years, and every two years, one-third of them retire. This way, the house doesn’t lose all its members at once.
Word Zone
Constituencies: Smaller areas into which a country is divided for elections
The main job of the Rajya Sabha is to review and suggest changes to the laws made by the Lok Sabha. In addition to elected members, the President can appoint individuals who excel in fields like arts, sciences, or social service to the Rajya Sabha. This adds extra knowledge and skills to their discussions.
The Rajya Sabha should consist of no more than 250 members - 238 members representing the States and Union Territories, and 12 members nominated by the President. The Vice President of India serves as the head of the Rajya Sabha and ensures the smooth functioning of the Rajya Sabha.
The Rajya Sabha stands as a representative body for the States and Union Territories of India, making sure that every part of the country has a voice in the national decision-making process.
The President is the head of state and the supreme commander of the armed forces. The President lives in a special house called the Rashtrapati Bhavan in New Delhi.
of state: Leader of a country
The President makes sure that everything in the country runs smoothly. A few roles of a president are:
• Sign bills that turn into laws.
• Represent India in international forums.
• Start and end the sessions of both Houses of Parliament, i.e,. Lok Sabha and Rajya Sabha.
• Appoint the governors of states, the Chief Justice of India, and other judges of the Supreme Court and High Courts, etc.
The President has the power to declare three types of emergencies: national, state, and financial.
While the President’s role is essential, they mostly follow what the Prime Minister and the government suggest. A president is elected for a five-year term, and they have the option to seek re-election for subsequent terms.
The Prime Minister is the head of the government and holds a prominent leadership position. He is not directly elected by the people but is appointed based on their leadership within the political party that wins the most seats in the Lok Sabha, the lower house of Parliament, during general elections.
The Prime Minister also heads the Council of Ministers, a group of key ministers who are responsible for various roles.
Together, they work to formulate policies and make important decisions for the country. One of the significant roles of the Prime Minister is to formulate policies that shape the direction of the nation. These policies cover areas such as the economy, foreign affairs, defence, and social issues.
On the international stage, the Prime Minister represents India, engaging in diplomatic relations, participating in global forums and building relationships with leaders from other countries.
During challenging times, the Prime Minister takes charge of crisis management. Whether it’s a natural disaster, economic downturn, or health crisis, they lead the government’s response to ensure the well-being of the citizens.
With significant decision-making authority, the Prime Minister plays a key role in shaping the legislative agenda, proposing new laws, and ensuring the effective implementation of government policies. Ultimately, the role of the Prime Minister is centred around public service. He works to improve the lives of the citizens, address their concerns, and contribute to the overall progress and prosperity of the nation.
The Union Government of India functions under the world’s largest written constitution, the Indian Constitution, which balances power between the central government and the states.

Just like the central government takes care of the whole country, each state in India has its own government, known as the State Government.
Every state has its own rules and laws decided by its Legislative Assembly, also known as the Vidhan Sabha. This assembly is like a mini-parliament for the state, and its members (called MLAs) are elected by the people of that state to represent their voices.
Legislative Assembly- Kerala
Legislative Council- Uttar Pradesh
Some states have an additional house called the Legislative Council or the Vidhan Parishad. This is like an Upper House.
In each state, there’s a Chief Minister, who is like the leader of the state’s government. They lead the state government and ensure everything runs smoothly.
The Chief Minister has a group of ministers known as the Council of Ministers, each with specific jobs like handling education, health, or finance.

Every state also has a Governor, who is like the head of the state, representing the central government. The Governor ensures that the state follows the rules and laws set by the central government and has certain powers to oversee the state’s administration.
The State Government looks after important things like education, healthcare, law and order, and roads, directly impacting the people in the state. They create rules and policies to manage these areas effectively. For spending money, the State Government plans where to use funds for schools, hospitals, roads, and other things that help the people in their state.
While the State Government manages things within its state, it also works closely with the central government to strike a balance between national laws and statespecific needs. They collaborate on various matters to ensure everything runs smoothly.

The Judiciary in India is divided into 3 bodies.
Structure of Indian Judiciary
The Supreme Court is the highest judicial body in India. It is located in New Delhi, the capital city of India. It acts as the final court of appeal in the country. This means that any legal decision can be appealed to the Supreme Court, and its judgment is final. It also protects the fundamental rights of citizens as guaranteed by the Constitution.
Supreme Court of India
In India, each state has a High Court. These courts are the highest judicial bodies at the state level.
They hear appeals from lower courts and also handle significant state-level cases.
These include District Courts and other lower courts.
They are the first level of courts where most legal cases begin. They handle a variety of cases, including civil and criminal matters.
The Supreme Court of India was established on January 26, 1950. It has the power to decide disputes between various governments in the country and hears appeals against the verdicts of the lower courts.
