6.On 21st March and 23rd. September there are equal days and nights.

Chapter.4: Maps


1. Maps are important than a globe because-:

1. A map provides us with detail information about a place.

2. A map is easy to carry.

3 When we want to study a place then it is helpful.

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

3.Political Maps-: Maps showing cities, towns & country boundaries are called political maps.

4.Thematic Maps-: Some maps focus on special information such as roads, forest, industries etc. are known as thematic maps.

5. There are three compounds of maps-:

1.Distance    2.Directions   3.Symbols.

6.Scale-: It is the ratio between the actual distance shown on the ground and a distance shown on the map.

7. There are four major directions-:

1.North    2.South 3.East.   4.West

These are called cardinal points.

8. Compass-: It is an instrument used to find out the main directions. (North).

9. Sketch-: It is a drawing mainly based on memory and observation and not to scale

10.Plan-: A plan is a drawing of a small area on a large scale.

11. The symbols are useful in reading maps as-:

1. Symbols give a lot of information in a limited space.

2. Symbols can be drawn easily and are simpler to read & understand.

3. We can collect information from maps with the help of symbols.

4. Symbols have a universal language that can be understood by all.

The Tibet plateau is the highest Plateau in the world. With the height of 4000 to 6000 meters.

Plateaus are very useful because they are rich in mineral deposits.

7.Formation of Plains-:

1. Most of the Plains are formed by rivers and their tributaries.

2. The rivers flow down the slopes of mountains and erode them.

3. They carry forward the eroded material.

4. Then they deposit their land consisting of stones, sand & silt along their courses and in their valleys.

By this plains are formed.
