Classify the northern plains on the basis of variations in the relief features explain the characteristics features of each of them

1. Bhabar - The rivers, after descending from the mountains, deposit pebbles in a narrow belt of about 8-16 km in width lying parallel to the slopes of the Shiwaliks. All of the streams disappear in this belt.

2. Terai - South of the bhabar belt, the streams re-emerge and form a wet, swampy and marshy region. This is a thickly forested region with an abundance of wildlife. 

3. Bhangar - The largest part of the Northern plain is formed of older alluvium. They lie above the floodplains of the rivers and present a terrace-like feature. They contain calcareous, rocky deposits known as Kankar.

4. Khadar - The newer, younger deposits of alluvium in the floodplains. They are renewed almost every year, and are fertile, hence ideal for growing rice and wheat.
