Northern Plains of India – UPSC

The northern plains have 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 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 an adequate water supply and favorable climate, it is agriculturally a very productive part of India.

They lie to the south of the Shivaliks, separated by the Himalayan Frontal Fault (HFF). The southern boundary is a wavy irregular line along the northern edge of Peninsular India. On the eastern side, the plains are bordered by the Purvanchal hills.
