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.
Q21. How are symbols on the maps important?
(i) It is not possible to draw the actual shape and size of different features such as buildings, roads, bridges, trees, railway lines or a well on a map. So, they are shown using certain letters, shades, colours, pictures and lines.

(iii) These symbols are universal language that can be understood by all as there is an international agreement regarding the use of these symbols which are called conventional symbols
