Q4. How has the northern plains of India been formed?Give a short description of it.

 

The Great Indian Northern Plains are formed due to the depositional activities of the three rivers- the Ganga, Indus and the Brahmaputra. Millions of years ago, the vast reserves of alluvium soil was deposited at the foothills of the Himalayan mountains. The three rivers flowed down the great mountains and deposited the alluvium soil in the northern plains making it one of the most fertile plains in the world.
