| The Northern plain has been formed by the interplay of the three major river systems, namely the Indus, the Ganga and the Brahmaputra along with their tributaries. This plain is formed of alluvial soil. The deposition of alluvium in a vast basin lying at the foothills of the Himalaya over millions of years, formed this fertile plain. It spreads over an area of 7 lakh sq. km. The plain being about 2400 km long and 240 to 320 km broad, is a densely populated physiographic division. With a rich soil cover combined with adequate water supply and favourable climate, it is agriculturally a productive part of India. |
| The rivers coming from Northern mountains are involved in depositional work. In the lower course, due to gentle slope, the velocity of the river decreases, which results in the formation of riverine islands. Majuli, in the Brahmaputra river, is the largest inhabited riverine island in the world. The rivers in their lower course split into numerous channels due to the deposition of silt. These channels are known as distributaries. |
