Q- Classify the Northern Plains on the basis of the variations in the relief features. Write characteristics each of any three of them.
Answer- On the basis of the variations in the relief features the Northern plain is classified into four parts:
1. Bhabar:
The rivers after descending from the mountains deposit pebbles in a narrow belt which is lying parallel to the slopes of the Shiwaliks. These small pebbles are known as Bhabar.
2. Terai:
The rivers and streams re-emerge and create a wet, swampy and marshy region to the south of Bhabar belt which is known as Terai. This was a thickly forested area but was later on cleared for cultivation on that field.
3. Bhangar:
The rivers after descending from the mountains deposit to form alluvial soil. The alluvial soil which is old deposit of the rivers is known as Bhangar. It is not more fertile than Khadar.
4. Khadar:
The rivers after descending from the mountains deposit to form alluvial soil. The alluvial soil which is newly deposited by the rivers is known as Khadar. It is more fertile than Bhabar and is a ideal soil.
