PREFACE ADDITIONAL READING All the information you need to successfully complete the year’s Geography is contained in this study guide. The following are recommended for enrichment: • Ranby, P, Johannesson, B, Monteith, (2013). Platinum Social Sciences Grade 7 Learner’s Book. Cape Town: Maskew Miller Longman.

• Any printed atlas.

INTRODUCTION Social Sciences is one subject, although each section (Geography and History) has its own study guide and facilitator’s guide.

Geography is more than a mere study of the earth, as was believed in the past. In fact, it is the study of both our human and physical environment. Geographers are interested in the natural processes that take place in various environments, human settlement and activities, our interdependence on our immediate environment and the impact that we have on that environment. But most importantly, geographers are fascinated with change. We live in an ever-changing world and therefore, the phenomena which we study are in an ever-changing environment.

This study guide will focus specifically on spatial literacy, patterns and trends, as well as on the reading and drawing of basic maps, using statement and linear scale. It will also cover a section on natural disasters caused by earth movement, population growth and change, and sustainable conservation of resources in South Africa. This is in accordance with the guidelines set out in the CAPS curriculum.

In order to get the most from this study guide, you should not merely learn the content that is provided. As geography is constantly changing, you are encouraged to study the world around you, broaden your knowledge with the use of the internet, libraries and magazines.

Most importantly, keep abreast of current affairs by reading or listening to the news at least three times a week. Keep an ‘articles book’ in which you can keep and analyse geographically pertinent events that are covered in the news. You may indicate the locations of these events on a map.

By the end of this study guide you should be curious about the world we live in, have a decent general knowledge of the places and natural forces at work on earth and understand the interaction between society and the natural environment. You should care about the planet and well-being of all who live on it. You should have the ability to think independently and support your ideas with sound knowledge, understand and work with a number of sources and observe and engage in phenomena in your own environment. You will have discovered a wealth of knowledge about people, places, events and issues using © Optimi

UNIT 1: Map skills LEARNING AIMS After you have completed this unit, you must be able to do the following: • Use grid references to locate places on a street map.

• Use a street map and compass directions to describe a specific route.

• Sketch a map of a local area.

• Use and define scale, differentiate between linear and statement scale, compare different types of scales and use those scales to calculate distance.

• Know the main lines of latitude and longitude and use them to locate where events happened on a world map.

• Stay abreast of current affairs and analyse certain events to ascertain certain information about those events, such as where, when, why and how an event occurred and what the effects of the event in question were.

INTRODUCTION The focus of this unit is to develop your ability to read and work with maps. You will investigate different types of maps including physical, political, sketch and road maps. You will also learn of the different elements of each of these maps and how to apply this knowledge in a practical sense. This unit will also teach you how to use different geographical skills and elements which will help you apply your knowledge, including a compass, linear and statement scale, grid references and lines of latitude and longitude.

The following definitions will help you to better understand the maps discussed in lesson 1.

Ensure that you now the definitions before starting with lesson 1.

LESSON 1: LOCAL MAPS AND STREET MAPS The types of maps below contain different details and are used to communicate specific information to the user. Each type of map will be discussed in detail during the lesson. The lesson will outline what each map is used for, as well as what type of information it provides to the user.

1.1

Types of maps

A map is a picture or representation of the earth’s surface, showing how things are related to each other by distance, direction, and size.

There are many different types of maps and each map is used for a specific purpose.

•

Political maps show international, national and provincial boundaries of a place and usually include the locations of cities, depending on the detail of the map.

Border between provinces, e.g., borders between Limpopo, Gauteng, Mpumalanga, the Free State and North West. Capital cities of Gauteng are indicated: Pretoria and Johannesburg.

A physical map shows the physical landscape features of an area such as mountains, rivers and lakes. Changes in altitude are usually shown using different colours and shades.

•

Rivers are indicated using thin blue lines, and mountains using brown.

Different shades of brown are used to indicate the height of the mountain range.

•

A topographic map also shows some physical features, however it uses contour lines and shows man-made attributes too. All topographic maps use symbols to show different attributes such as roads, dams and power lines.

Legend at the bottom of the topographic map indicates which symbol is used for each attribute on the map, e.g.:

Climate maps use colour to show information about the climate in a specific region.

The climate of an area is the basic weather pattern and precipitation over a period of time.

The colours give an indication of the temperature in a specific region over a specified period of time, e.g.: Red:

indicates average temperatures of 7,5 °C and less in a specific region.

Blue: indicates average temperatures of between 7,5 °C and 10 °C in a specific region.

Brown: indicates average temperatures of between 10 °C and 15 °C in a specific region.

White: indicates average temperatures of 15 °C and higher in a specific region.

Characteristics of maps

Each detailed map should contain the following characteristics: • A bird’s eye view: Because maps are flat, they should give you a bird’s eye view of a location, in other words, a view as seen as if you are looking down on the map.

•

Direction: All maps should have an arrow marked ‘north’. This helps you work out the other compass directions and ascertain the orientation of the map, i.e., north, south, east and west. On the following page is an illustration of a wind rose showing the 16 cardinal points of a compass.

•

Place/location: A direction, topographic or street map indicates exactly where a person is going. All buildings, rivers, roads, etc. should be clearly marked.

However, these elements cannot be indicated on a world map. The details shown depends on the purpose of the map.

•

Symbols: We can show some detail by using certain pictures to show landmarks or important structures. A cross may indicate a hospital, a capital ‘P’ a police station, or a dotted line may indicate power lines. These signs can only be understood if the map includes a key or a legend.

Area

Designation Erosion; sand Perennial water Swamp and marsh Orchard or vineyard Wooded area Built-up area (high, low density) Cemetery; grave

•

Key/legend: A key or legend is a little square on the map which explains each picture, sign and symbol, e.g., bridge.

•

Scale: Naturally we cannot realistically represent an area kilometres wide on an A4 piece of paper. Therefore, all maps are reduced representations of what exists in the real world, e.g., 1 km of reality has been reduced to 1 cm on the map. There are different types of scales we can use, e.g., word scales, ratio scales and linear scales. Each of these are explained in detail in Lesson 3.

FOR THE CURIOUS To determine direction, you need a compass. Follow these instructions to make your own compass.

MAKE YOUR OWN COMPASS There are a number of videos on YouTube that can help, e.g., https://goo.gl/oVnHa2 © Optimi

•

First identify the four cardinal points. In order to remember the order of the four main cardinal points, think ‘never eat silk worms’ which represents north, east, south, and west.

•

Then fill in the halfway point between each of the main points. Make sure you always start with north and south before east and west as they are more important, e.g., if you are labelling the point which is halfway between east and south, the direction would be south-east or SE, not east-south.

•

Then for the rest of the points, write the main direction which is closest followed by the halfway mark, e.g., the direction between southwest and west would be west-south-west or WSW, as west is your main direction.

However, if the point you are labelling is closer to south, you would label it south-south-west or SSW, as the main direction it is closest to is south.

Most maps are divided into a grid system, to make it easier to find a specific point of interest. These maps use variables down both sides of the map, so that each point has two variables, from north to south and from west to east. The world is also divided into a grid system called coordinates, which will be discussed in detail in lesson 5. However, the grid system is very similar. Look at the following map, which has been divided into a grid system.

We can easily find a place by using a grid system. The columns are represented by numbers, which appear at the top and/or bottom of the page. The rows are identified by letters appearing on the left and/or right of the map. Any grid can quickly be identified using a letter and a number, e.g., D4. Go to row D, then move to column 4. Where these two (row and column) meet, you’ll find D4.

Reference books and guides generally have an index at the back, which sorts the contents alphabetically. This makes it far easier to find specific information. Map books are no different. There is an index of road names and important buildings which gives the grid reference and page number of each name.

On the other hand, a contents page, or table of contents, is in front of the books, and provides the content in which it appears in the book, usually with page numbers.

How to find places and explain routes using a street map

The following definitions will help you to find places and explain routes using a street map.

DEFINE Departure point

The starting point of a journey.

Destination

The place where someone or something will end up.

Profusely

When something is occurs or appears in large amounts, e.g., trees or rivers.
