Which of the following physiographic sub-divisions of the Great Indian Plains lies adjacent to the foothills of the Shivaliks, characterized by a narrow, porous belt of coarse pebble and gravel deposits where small streams temporarily disappear underground?

💡 Solution & Explanation

The Bhabar is a narrow eight to sixteen kilometer wide porous belt lying along the base of the Shivalik hills where rivers deposit heavy boulders and coarse sediments brought down from the mountains, causing streams to sink underground. South of the Bhabar lies the Terai region, where these underground streams re-emerge to create marshy, wet tracts. Bhangar represents older alluvial terraces, while Khadar consists of younger floodplains renewed annually.
