3. Atlas:-When many maps are put together we get an Atlas.

4. Physical Maps:- Maps showing natural features of the earth such as mountains, plateaus, plains, rivers, oceans etc. are called physical or relief maps.

5.Political Maps:- Maps showing cities, towns and villages, and different countries and states of the world with their boundaries are called political maps.

6.Thematic Maps:- Some maps focus on specific information; such as road maps, rainfall maps, maps showing distribution of forests, industries etc. are known as thematic maps. Suitable titles are given on the basis of information provided in these maps.

7. There are three Components of Maps – distance, direction and symbol.

8.Distance:-Maps are drawings, which reduce the entire world or a part of it to fit on a sheet of paper. Or we can say maps are drawn to reduced scales.

9.Scale :- Scale is the ratio between the actual distance on the ground and the distance shown on the map. For example, the distance between your school and your home is 10 km. If you show this 10 km. distance by 2 cm on a map, it means, 1 cm on the map will show 5 km. on the ground. The scale of your drawing will be 1cm = 5 km. Thus, scale is very important in any map.

10. Small Scale Map :- When large areas like continents or countries are to be shown on a paper, then we use a small scale. For example 5 cm. on the map shows 500 km. of the ground. It is called a small scale map.

11.Large Scale Map:- When a small area like your village or town is to be shown on paper, then we use a large scale that is 5 cm. on the map shows 500 metres only on the ground. It is called a large scale map.

12.Direction

● North Line:- Most maps contain an arrow marked with the letter ‘N’ at the upper right hand corner. This arrow shows the north direction. It is called the north line.

● There are four major directions, North, South, East and West . They are called cardinal points. Other four intermediate directions are north-east (NE), south-east(SE), south-west (SW) and north-west (NW).

13. Symbols:- It is the third important component of a map. It is not possible to draw on a map the actual shape and size of different features such as buildings, roads, bridges, trees, railway lines or a well. So, they are shown by using certain letters, shades, colours, pictures and lines These symbols give a lot of information in a limited space.

14. Conventional symbols:- There is an international agreement regarding the use of these symbols. These are called conventional symbols. Some of the conventional symbols.
