Question
How were the northern plains formed?
✓
Answer
The northern plains have been formed by the interplay of the three major river systems-the Indus, the Ganga and the Brahmaputra along with their tributaries.
The Himalayan uplift out of the Tethy’s sea and subsidence of the northern flank of the Peninsular plateau resulted in the formation of a large basin. In due course of time, this depression gradually got filled with the deposition of the sediments by the rivers flowing from mountains in the north. A flat land with extensive alluvial deposits by these rivers led to the formation of the Northern Plains of India.
With a rich soil cover, combined with adequate water supply and favourable climate, it is agriculturally a very productive part of India.
