1 Where do fires do the most damage?

"Spain had the worst fire season of the century in 2022. Forest fires destroyed around 300,00 hectares.". The day after reading the news, Laura came to class to discuss it with her teacher. Her grandfather lives in Zamora, the province worst affected by the fires, and has lost some of his property. She wants to understand how this happens and, most of all, if there is anything she can do to prevent a situation like this in the future.

What do you think?

Why do you think forest fires happen? Do you think they are natural or provoked? What action is taken to prevent them? What are the consequences?

Context

In this unit...

Target in action

Record a video talking about the increase in fires and giving advice on how to prevent fires in our local countryside.

The General Directorate for Civil Protection and Emergencies of the Ministry of the Interior says that 95 % of forest fires are caused by people, who are not careful.

Why do we check the weather forecast every day?

The weather affects our everyday life. It tells us what type of clothes to wear, if we will need an umbrella, sunglasses...

Why is the atmosphere so important?

The atmosphere is the layer of gases surrounding the Earth, primarily nitrogen, oxygen and carbon dioxide. It is essential for life to exist on our planet because:

• It filters dangerous solar radiation.

• It regulates the planet's temperature, making it habitable.

• It contains gases necessary for breathing and photosynthesis of living beings (oxygen and carbon dioxide).

Atmospheric phenomena

Atmospheric phenomena are things that happen naturally in the atmosphere: wind, clouds, precipitation, etc.

To find a summary of the unit, watch the video 'Let me tell you' on anayaeducacion.es

The air in the atmosphere moves because of temperature changes, resulting in wind

10
1
When temperatures go down, the condensed water in the clouds falls to the earth's surface as rain (liquid water), snow or hail (solid water). Clouds are formed when water droplets condense in the atmosphere after evaporation.

How is the weather?

Atmospheric phenomena determine atmospheric or meteorological weather , understood as the state of the atmosphere at a time and place.

Atmospheric weather changes a lot and we study it in meteorology . The aim of meteorology is to forecast the weather in 24 or 48 hours and to produce a short or medium-term weather forecast.

We see analysis and predictions everyday in meteorological maps or weather maps

One of the most special atmospheric phenomena is the rainbow. Rainbows happen when it rains and the raindrops act as mirrors, dispersing and splitting the light. Polar auroras is another, which you can only see at specific locations on the planet. They are the result of the interaction of the earth's magnetic poles and particles transported by solar wind.

1 Write around List the reasons why the atmosphere is important for living things.

2 Which atmospheric phenomenon is this?

• It is formed because of the condensation of water droplets in the atmosphere.

• Condensed water in the clouds comes down to the surface.

• Movement of the air in the atmosphere.

3 What makes you say that? Look at the weather map and describe the weather in your region.

Take note!

Recently, there is more extreme atmospheric or meteorological phenomena such as snowfalls, heat waves, torrential rain, tornadoes, etc.

What weather elements can influence fires to spread?

What data should be considered when defining a high-risk fire area?

What is climate?

Climate is a set of frequent atmospheric conditions at a particular location that is determined after a study of the atmospheric weather in that area over several decades. This study helps establish the frequent behaviour of atmospheric phenomena at a particular location.

Weather elements

Weather elements are the set of components that characterise the atmospheric weather and how they interact with each other. They are essential for reliable weather forecasting.

Weather elements

Temperature . This is the quantity of heat energy accumulated in the atmosphere. It is measured in degrees Celsius (ºC), with a thermometer

Precipitation . This is water falling on the earth's surface. It can be in a liquid or solid state. It is measured in litres per m 2 with the rain gauge

Humidity. This is the quantity of water vapour in the atmosphere. The higher the temperature, the lower the humidity. It is measured with the hygrometer

1 Name the weather elements and the instruments used to measure each of them.

2 Pencils in the middle What are climatic factors? Name the ones that you think influence where you live and which ones do not.

3 Create your own weather station in class.

Cloud cover . It is the quantity of clouds.

Wind . This is the movement of air in the atmosphere. Its speed is measured with the anemometer, in metres per second (m/s), and its direction is shown by a wind vane

Atmospheric pressure

This is the weight that a mass of air presses on the earth's surface. It is measured in millibars, using a barometer

12 2

Climatic factors

Climatic factors are the climatic conditions of a specific area. Depending on these factors, the elements of the climate will be different and so will the climate.

To learn more about meteorological elements, watch the video "The weather station" on anayaeducacion.es.

The temperature reduces by 1 °C for every 100 metres of altitude.

This is the distance from any point on Earth to the equator or 0 ° parallel. The climate of an area is warmer when it is closer to the equator and colder when it is further away.

This is the height that any surface reaches above sea level. Altitude affects temperatures: the higher the altitude, the lower the temperature.

The water in the seas and oceans warms slower than the land, so it regulates the temperature of nearby areas, making them less extreme. The influence of the sea also affects wind and humidity.

Relief is the diversity of shapes that the earth's crust forms, such as mountain ranges, plains, valleys, etc. The climate in mountainous areas will be different from lowland areas.

Which areas of Spain are most at risk from fires?

Not all parts of Spain have the same climate, so the risk of fire varies.

Climates of Spain

Spain is in the temperate climate zone of the Earth, because of its latitude.

All the climatic factors mentioned mean that Spain has a characteristic climatic diversity.

Climate and fire

The continental climate covers most of the peninsular surface. Temperatures are extreme, very cold in winter and very hot in summer, because of the limited influence of the sea. Precipitation is abundant in autumn and spring, sometimes torrential, and very low in summer.

In the southern sub-plateau and a large part of Andalucía there is a variety, the continentalMediterranean climate , with less extreme temperatures.

The oceanic climate is found in the north of the peninsula. Its main characteristic is cool temperatures in winter and mild in summer. Precipitation is abundant throughout the year, but less in summer.

1 Draw a map of the climatic zones of Spain in your notebook.

2 What is the climate in the area where you live? What are its characteristics?

The mountain climate is found in high mountain areas. Temperatures are normally cold, even in summer, and go below freezing in winter. Precipitation is frequent, and snow falls in winter.

The subtropical climate in Spain is found in the Canary archipelago, because of its geographical location closer to the warm zone. Temperatures are usually warm all year and there is little difference between summer and winter. Precipitation is low, but higher in the northern islands than in the south.

The Mediterranean climate is located in the coastal areas of the south and east of the peninsula. This climate has mild temperatures in winter and hot temperatures in summer, more than 2730 °C. Precipitation is irregular, mostly in spring. Precipitation can also be torrential.

Greenpeace says Spain is one of the European countries most affected by forest fires. Investing in prevention is necessary.

We show the climate

Can we show the fire risk during the year?

Climatology is the science that studies the climate and how it changes over time. Although it uses the same parameters as meteorology, its objective is not the same, as it does not make immediate forecasts, but studies long-term climatic characteristics.

Climographs

Climographs are graphs that represent the annual evolution of two of the elements of climate: temperatures and precipitation. They show the monthly average temperature and the monthly volume of precipitation.

These data are shown in a table which can then be represented in a graph.

How to make a climograph

Monthly average temperatures are shown with a red dot, which is connected with a red line. This information is collected using thermometers.

1 Look at Santander's climograph and answer the questions.

• Which month had the most precipitation?

• Which months had temperatures more than 10 ° C?

• What would you say the rainfall is like during the summer months?

• What are the differences with the climate where you live?

Precipitation is represented at twice the rate of temperatures using blue bars. To collect this data, rain gauges are necessary.

2 Look for information and make a climograph for your town or your provincial capital.

Take note!

Wind makes it very difficult to extinguish fires, as it causes them to spread faster.

Which landscapes are most affected by fires?

Which plant species are most at risk from fires?

Landscapes

Landscape is an area of the earth's surface resulting from the interaction of the different factors present in it (climate, flora, fauna, relief, etc.) which can be observed together from a certain point.

As we saw in this unit, climatic factors mean that in some areas there are higher or lower temperatures, more or less rainfall, less or more humidity or altitude... All these factors, with the relief, flora and fauna, make up different climates, and different types of landscapes.

1 Match the characteristics of each type of landscape with its corresponding climate.

2 Using different types of paper, create a two-part map where the map of landscapes can be placed on top of the map of climates. For example, you can use cardboard for the climate map and tracing paper for the landscape map so that one can be placed on top of the other.

Let's prevent fires!

Do a search on the Civil Protection website and make a list of the measures you consider most important to prevent forest fires.

Transition landscape. This is found in continental and continental-Mediterranean climate zones. It has trees and combines deciduous and evergreen. These forests have adapted to the frequent droughts of the continental climate in the warm months.

Oceanic landscape. Located in areas with an oceanic climate. This landscape has tall deciduous trees, such as oak and beech, which lose their leaves in autumn. This area of Spain is known as green Spain, as the vegetation is also green because of the abundance of precipitation.

Mountain landscape. This type of landscape is located from the upper limit of a forest to the top of a mountain. Vegetation is limited because of the climate of these areas and is mosses or small bushes.

Mediterranean landscape. This type of landscape is in areas with a Mediterranean climate. The vegetation is evergreen trees, such as pines and holm oaks, because of the irregular precipitation and high temperatures. The trees are not very tall, but the leaf cover is generally denser than in the Atlantic forest.

Take note!

The main causes of fires include climate change, lots of scrubland and poorly managed urbanisation of woodland areas.

We study how the climate is changing

What GIT (or GIS) features can be useful when managing a forest fire?

Climate change

Climate change is a change in climate, because of human activity, that changes atmospheric composition, plus naturally occurring changes in the planet's climate.

Climate change Causes

• Increase in greenhouse gases, caused by activities that use fossil fuels: transport, heating, factories, etc.

• Deforestation, or destruction of forests, which limits nature's ability to absorb carbon dioxide.

• Excessive consumption by the population. Our lifestyles have a major impact on the planet's health.

Speaking. Talk to a friend about the possible consequences of climate change if we don’t change our behaviour.

Writing. Write a list of possible actions we can do to reduce the negative consequences of climate change.

Consequences

• Increasing temperatures and fires.

• Devastating extreme weather events, such as floods or extreme droughts.

• Rising sea levels because of melting ice and warming water.

• More endangered species.

• Depletion of natural resources.

• More diseases and health problems.

Mitigation and adaptation measures

To combat climate change, reduce its negative consequences and benefit from the opportunities it can create, a series of measures have been put in place: Improving energy efficiency, focusing on renewable energies; reforesting forests; promoting public transport and sustainable mobility; and creating protocols for action for climate emergencies.

Effects on our community

Average temperatures have risen by almost two degrees in recent years.

Also, precipitation has changed, which is no longer as abundant or distributed seasonally in the same way. There are more droughts in the last five years, drought periods have increased over the last five years, and torrential rains are more frequent.

This has a direct impact on our landscapes.

GITs

Geographic information technologies (GIT) are a set of technologies that make it easier to collect, use and analyse environmental data the collection, use and analysis of environmental data, such as remote sensing (RS), global positioning systems (GPS) and geographic information systems (GIS).

These technologies use GPS to make maps of a specific area and connect them to the most relevant study aspects.

This makes it easier to analyse things such as precipitation, pollution levels and the relationships between them.

GIT in meteorology and climatology

Thanks to GIT, extreme meteorological phenomena such as hurricanes, torrential rains, etc. can be identified and prevented.

Maps are produced that predict the approximate risk level by adding hazard and social and economic factors in a specific territory.

GIT can also be used to collect data on climate change evolution, such as locating areas with abnormal temperatures, establishing how natural atmospheric processes affect global warming, creating predictive models of its consequences, etc.

1 I think, I’m interested, I investigate What is the relationship between climate change and the increase in fires in recent years?

2 Investigate how other activities that can use GIT. Which of these applications do you find most useful? Why do you think so? Discuss with your classmates.

3 Why are GIT useful for climatology and meteorology?

4 Search for information on cases where GIT has been used as a tool in fire containment or firefighting. Share the results of your search with the rest of the class.

Take note!

GIT has designed a 3D simulator that predicts how a fire will behave, which areas it will affect and where it will move. All this information is shown on a map, meaning we can make better decisions.

2 Is water undervalued ?

Carmen is a Spanish girl who studies 4th Grade Primary School in a class with other classmates. They did some research on the latest UNICEF reports for their group work. The report Carmen has found most interesting is a 2019 report on inequalities of access to water around the world. This report says approximately 2.2 billion people around the world do not have access to safe drinking water facilities. Also, this problem is increasing because of the rising pollution of freshwater sources. Sadly, children are the first to suffer the consequences of this situation.

What do you think?

What would happen if we suddenly had no drinking water in our homes and had to travel several kilometres to get it? Why do you think children suffer the most from these problems?

Context

Target in action

Make a sign with a catchy slogan to make people conscious of the importance of saving and not polluting our available water.

Where is water collected on our planet?

If water covers more than half of the earth's surface, why is access to it so limited in some countries?

The blue planet

Our planet looks blue when you look from space. This is because almost three quarters of the Earth's surface is covered by water, almost all of it is salty.

The hydrosphere is the Earth's water. Without it, life on Earth would be impossible.

• Humans, animals and plants need water to survive. Many living things live in it.

• The water in oceans and seas absorbs heat from the sun, helping to maintain and moderate the temperature of the planet.

Water can be found in nature in three states or forms: solid, liquid and gaseous. Water will change its state depending on how much cold or heat is applied.

Water states and its changes

Solid state

This is how water is found in seas, rivers or lakes. It is the most abundant. This is what water is like when it is heated and turns into steam. Changing from a liquid to a solid because of the effect of cold. Changing from gaseous to a liquid because of the effect of cold.

The water cycle

Water is always moving around the Earth. Thanks to changes in its state, the water cycle takes place.

Condensation

As the water vapour rises, because of low temperatures, it condenses into small droplets that form clouds.

Take note!

Only 0.007% of the Earth's water is drinkable, and this amount is decreasing every year due to pollution.

Precipitation

As the clouds grow larger and larger, their weight and the drop in temperature cause the droplets to precipitate in the form of rain, snow or hail.

Evaporation

The liquid water present in the large bodies of water evaporates thanks to the heat of the sun and rises into the atmosphere in the form of water vapour.

1 Ideas pool Why is the Earth known as the blue planet? What is the hydrosphere?

2 Think and share in pairs Explain the importance of the hydrosphere.

3 Investigate at what temperature water melts and solidifies.

Accumulation

Water from precipitation accumulates again, forming bodies of water. Some of it filters down, forming groundwater, some of it stays on the surface, starting the water cycle all over again.

To better understand the water cycle, watch the video "The drop of water" on anayaeducacion.es.

4 Draw a diagram of the water cycle in your notebook.

5 Name the states of water and write what change is taking place in each case:

• Marina leaves the house and it starts to rain.

• Desiree and Juanlu are skating on a frozen lake.

U2 27

How is water divided up on Earth?

Which bodies of water do we extract the water we use daily?

Surface water and groundwater

The waters that make up the hydrosphere can be surface water or groundwater .

Surface water

Surface waters are those found on the earth's surface, resulting from the accumulation of precipitation or from the escape of groundwater to the surface. They can be inland or marine.

Marine waters are bodies of salt water, such as the seas and oceans. Two phenomena happen in them:

• Ocean currents. These are movements of water caused by changes in temperature and level of salt, by the wind or by the earth's rotation.

Inland waters are bodies of fresh water. They can be moving, as in rivers and streams, or still, as in lakes.

Groundwater

Groundwater is the water that cannot be seen. It is located below the surface of the earth. It filters through porous soils or cracks in rocks and accumulates in the earth's interior, forming aquifers and underground rivers.

• Tides. These are changes in sea level caused by the gravitational pull of the moon and the sun on the earth.

Sometimes they are extracted artificially by digging wells

These waters form underground caves and tunnels. Occasionally, they rise to the surface, creating to natural springs or fountains.

28 2

Less and less water is available!

Look at the graph, think and answer:

• What is the trend in the evolution of available water, is it increasing or decreasing?

• In which year was the highest amount recorded? And the lowest?

• How many years are there between the two dates?

• What is the approximate difference between the two?

Water usage

Humans use water for activities such as agriculture, livestock farming, industry, etc. We also use it for our own consumption (drinking, hygiene, food, cleaning, etc.).

Stored water

Dams are built on rivers to store fresh water in reservoirs to provide water when it is not raining and to produce electricity.

1 What two types of surface water are there?

2 Write two examples of bodies of fresh water and two examples of salt water.

3 What is the difference between groundwater and surface water?

Evolution of available water in Spain

drinkable For its puri cation

Seawater treatment may be a solution to the increased lack of freshwater, but its economic and energy costs are too high for it to be a cost-effective solution.

Before it can be used for human consumption, water must be treated, which is why desalination and purification processes are carried out.

What are rivers like?

Do humans benefit from the features and elements of rivers?

What is a river?

A river is a freshwater stream made by precipitation or snowmelt that starts in the mountains and flows into the sea, a lake or another river.

Elements of a river

We can distinguish different parts or elements of a river: source, course and mouth

Source. Place where a river starts or springs. It is normally in mountainous areas.

Upper course. The section closest to the source. The waters flow very fast because of the gradient.

Course. The course of the river from its source to its mouth. We divide it into the upper, middle and lower course.

Middle course. The central section of the course. The gradient decreases and the speed of the water decreases.

Tributary. River that flows into another river.

Lower course. The section closest to the mouth of the river. There is hardly any gradient and the water flows slowly. The river forms very sharp bends, called meanders

Riverbed. The land where a river flows. Watershed. Set of lands whose rivers flow into the same sea or ocean.

Characteristics of a river

The main characteristics of a river are length , flow and regime

These characteristics depend on two factors : relief , which determines the length and velocity of the water, and climate , which determines the flow and regime.

1 List the elements of a river.

2 In your notebook, define these concepts: tributary, riverbed, mouth and flow .

3 Do you know if there are any reservoirs

The waters around me

Look for information and make a list of the bodies of freshwater in your area.

It does not need to be only rivers, but also lakes, ponds, aquifers, etc.

Length. The distance from the source to the mouth of the river. Rivers can be short or long.

4 Classify these terms according to whether they are elements or characteristics of a river: regime - course - mouth - flowsource - length.

Flow. The amount of water that the river carries during a particular section and at a particular time.

Regime. Variation of the flow throughout the year. Regular regime if it varies little; irregular regime if it varies a lot, or even dries up.

Mouth. The final section of a river. Its waters flow into a sea, ocean, lake or another river.

What are the most important rivers in Spain?

How well preserved are Spanish rivers?

The three watersheds

Spain is divided into three hydrographic watersheds : the Cantabrian watershed, the Atlantic watershed and the Mediterranean watershed.

These are rivers that flow into the Atlantic Ocean, which are the majority because of the gentle westward slope of the Central Plateau. We have two groups:

- Galician rivers They are short and regular. The most important are the Tambre, the Miño and its tributary, the Sil

- Rivers of the Meseta and the Guadalquivir depression. These are long and irregular rivers. The main ones are the Duero and the Tajo , the Guadiana and the Guadalquivir

There are no permanent rivers in the Canary archipelago. When it rains in storms, the water flows in channels known as ravines

To better understand landforms, watch the video "The rivers of Spain” on anayaeducacion.es.

Rivers that flow into the Cantabrian Sea They are short rivers, as they start very close to the sea, in the Cantabrian mountain range. Thanks to the rainy climate, they are regular rivers. The main ones, from east to west, are the Bidasoa, the Nervión, the Besaya, the Nalón, the Navia and the Eo

1 How many watersheds are there in Spain? Draw a map of Spain and point out the main rivers in each one.

2 In pairs, play a game where you say the name of a river out loud. Your partner has to guess which watershed it belongs to.

3 Look at the map and write down: two tributaries of the Duero, one of the Tajo, one of the Guadiana, one of the Guadalquivir and two of the Ebro.

4 Draw up a diagram or conceptual map with the basic information about the rivers of Spain.

They are rivers with different lengths and regimes. There are two groups:

- Eastern rivers. From north to south, the main ones are the Ter; the Llobregat; the Ebro , which is the largest in Spain; the Turia ; the Júcar and the Segura

- Southern rivers. These are short, as they start near the coast, in the Penibetic mountain range. The most important are found in Andalucía and are, from east to west, the Almanzora, the Guadalfeo and the Guadalhorce

There are no permanent rivers in the Balearic archipelago either. When there are strong storms, streams called torrents are formed.

Take note!

Are we taking care of our rivers?

Think with a partner 3 eveyday actions we can take to prevent river pollution.

More than half of Spain's rivers are polluted, because of toxic fertilisers or chemicals. There are also other more common pollutants, such as household appliances, masks, furniture or debris.

Are we using water correctly?

Is it the responsibility of all citizens to care for water and use it correctly?

Water is essential for the life of all living things on the planet. Apart from drinking, people use water for many other activities.

This natural resource may seem unlimited to us, but not using it correctly or over-consumption could lead to its drying up and have very negative consequences. So, it is very important that we use water intelligently.

Uses of water

When we use water to clean streets, fill public fountains, water parks and gardens or put out fires, we are making a public use of it, as it is used for the benefit of all citizens in general.

Who consumes less water?

Look at the graph and answer:

• Which autonomous community spent the most water in 2020?

• Which autonomous community had the lowest consumption in 2020? Why do you think this is?

• Which number is closest to your region's consumption in 2020?

Language Bank

Speaking. Go over the tips for saving water with a friend and say which ones you like.

Writing. Organise the tips into two groups: the ones you like and the ones you don’t. Write a sentence explaining why.

When we use water at home, we are using it for domestic purposes, for example, when we drink, take a shower, brush our teeth, wash dishes and clothes, etc.

Water saving tips

Instead of taking a bath, take a shower. Remember to turn off the tap while applying soap.

Run the washing machine and dishwasher only when they are completely full.

Don't leave the tap running while soaping the dishes. Use less detergent to pollute less.

Turn off the tap when brushing your teeth.

TARGET IN ACTION

Awareness of the importance of water

1 Reflect on the negative effects that our everyday actions can have on water using the Consequences and Results (C&R) thinking technique. These reflections will provide you with ideas for your banner slogan to raise awareness about the good use and care of water.

If you do something (play, do sport, rest, share, wrap up warm, eat sweets, don't wrap up warm)...

Long-term

What is likely to happen? What consequences will it have? What will be the resullts?

For you ?

For others

- Peers: for classmates, friends, brothers and sisters...

- Adults: for teachers, parents, grandparents...

Short-term

What is likely to happen? What consequences will it have? What will be the resullts?

For you ?

H ow did I learn?

1 Have you learned anything new? What images do you remember? What did you like most about what you learned? How useful is what you have learned? How will it help you in your everyday life?

- Peers: for classmates, friends, brothers and sisters...

- Adults: for teachers, parents, grandparents...

Think about this!

Do you think it is fair that some people have access to clean water and others do not?

Who do you think is to blame for this situation? Would it be the same people who could find a solution?

What do you think will happen in 50 years' time if drinking water supplies continue to decline and we continue to pollute them?
