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

- Scale is the ratio between the actual distance on the ground and the distance shown on the map.
- 5 cm. on the map shows 500 km. of the ground. It is called a small scale map.
- 5 cm. on the map shows 500 metres only on the ground. It is called a large scale map.

- A sketch is a drawing mainly based on memory and spot observation and not to scale.
- A plan is a drawing of a small area on a large scale.
