Question

Why the Northern Plains are called the depositional plains?

Answer 1

Hey there

Northern plains are called the depositional plains because they are formed due to the deposits brought down by the flowing rivers- Indus, Ganga and Brahmaputra. The sediments (alluvium) brought down by the flowing river deposits in the north plains and makes the plains fertile.

Hope this helps!

Cheers!

Answer 2

The Northern Plain was formed by the deposits brought in by the three major rivers and their tributaries. Alluvium was deposited at the foot–hills of the Himalayas for millions of years. These deposits are now the fertile Northern Plains. Alluvium is soil or sediments deposited by a river or other running water.
