Essential Features Of Maps ( class- 6 )

This presentation gives us an idea of various geographical features depicted on a map.

1. Essential features of maps Chapter 2

2. Maps A map is a symbolic representation of selected characteristics of a place, usually drawn on a flat surface . Two essential features of maps are: Title Direction

3. Title The map title tells us what kind of information is provided in it.

4. Direction Cardinal directions N - NORTH E – EAST S – SOUTH W – WEST

5. Intermediate directions The directions in between the cardinal directions are the intermediate directions. North-east(NE) North-west(NW) South-east(SE) South-west(SW)

6. Scale Verbal scale States the ratio One inch equal five miles Linear scale Helps in direct measurement. |---------|---------|---------| Representative fraction scale Shows as a ratio or fraction. 12:22 or 12/22 1 inch (on the map)and 24000 inches (on the earth)

7. Legends The common signs and symbols that are internationally accepted and used in maps are called conventional symbols. Every map has a legend which explains the different colours and symbols used in it.

9. River A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river.

10. Meanders A meander is a curve in a river. Meanders form a snake-like pattern as the river flows across a fairly flat valley floor. The position of the curves changes over time.

11. Tributaries A tributary is a river or stream that feeds into a larger body of water.

12. Distributaries A branch of a river that does not return to the main stream after leaving it.

13. Delta A river delta is a low-lying plain or landform that occurs at the mouth of a river near where it flows into an ocean or another larger body of water.

14. Fold mountain Fold mountains are mountains that form mainly by the effects of folding on layers within the upper part of the Earth's crust.

15. Block mountain Fault-block mountains are formed by the movement of large crustal blocks when forces in the Earth's crust pull it apart.

16. Grid A network formed by the criss-crossing of vertical and horizontal lines on a map or a globe to locate a place.

17. Two types of grid: Parallels of latitude: imaginary circular lines drawn horizontally between the two poles and parallel to each other. Meridians of longitude : imaginary lines drawn vertically from the north pole to south pole.
