Explanation:
From the north to the south, these can be divided into three major zones: the Bhabar, the Tarai and the alluvial plains. Bhabar is a narrow belt ranging between 8-10 km parallel to the Shiwalik foothills at the break-up of the slope where the streams and rivers coming from the mountains deposit heavy materials of rocks and boulders.
The Alluvial Plains are divided further into Khadar and Bhangar regions.
