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.
