CBSE Class 6 Geography Chapter 4 Notes Understanding The Lesson
1. A map is a representation or a drawing of the Earth’s surface or a part of it drawn on a flat surface according to a scale.
2. Maps are useful to us for various purposes.
3. When many maps are put together we get an Atlas.
4. Maps are different types such as Physical Maps, Political Maps, Thematic Maps.
5. There are three components of maps:
- distance
- direction and
- symbol
6. A scale is needed to represent a large distance in a small distance on paper. Actually, scale is the ratio between the actual distance and the distance shown on the map.
7. When large areas like continents or countries are to be shown on a paper, then we use a small scale, it is called a small scale map. In the small scale map we used large 100 km of distance in some cm. or mm.
8. When a small area like village or town is to be shown on paper, then we use a large scale, it is called large scale map. In the large scale map, we use distance of metres in some cm. or mm.
9. Direction Maps are also very useful. These maps help us to find out a place. There are four major directions – North, South, East and West. They Eire called cardinal points.
10. Other four intermediate directions are – North-East(NE), South-East(SE), South-West (SW), and NorthWest (NW).
11. We can find out the direction of a place with the help of a compass. It is an instrument used to find out main directions. It is a magnetic needle which always points towards north-south direction.
12. Symbol is also an important component of map. Everything or object cannot be represented on the paper. For this purpose, symbols are used. Symbol contains letters, shades, colours, pictures, lines etc.
13. Maps have a universal language that can be understood by all. There is an international agreement regarding the use of these symbols. These are called conventional symbols.
14. Various colours are used for the same purpose. For example, blue is used for showing water bodies, brown for mountain, yellow for plateau and green for plains.
15. A sketch is a drawing mainly based on memory and spot observation and not according to scale.
16. A plan is a drawing of a small area on a large scale. A large scale map gives lot of information, which cannot be shown on a map.
