Explanation

Where Himalayan streams and rivers emerge from the mountains, they deposit their heavy load of rocks and boulders in the Bhabar - the narrow, porous, pebble-strewn northernmost belt of the Indo-Gangetic plain, unsuitable for agriculture. Khadar is new alluvium, Bhangar is old alluvium, and the Terai is the marshy belt south of the Bhabar.
