Answer
The Northern Plains have been formed from the alluvium that the mountain rivers deposited here.
This turned the soil on the surfaced land fertile for growing a rich harvest of variety of crops.
This led to the development of the Indus River Valley Civilisation. The rich soil was further aided by favourable climate and constant water supply from the rivers.
Between the mouths of the Indus and the Ganga-Brahmaputra, the North Indian Plain covers a distance of 3200 km. It is 300 to 150 km wide at some places.
The North Indian Plains have the Indus river system in the west and the Ganga-Brahmaputra river system in the east. The first includes Jhelum, Chenab, Ravi, Beas, Satluj.
The Indus flows into the Arabian Sea. The second includes Ganga, its tributaries and the Brahmaputra which combine as Meghna as they drain into the Bay of Bengal.
They form the world’s largest and fastest growing delta. The difference in relief has led the North Indian Plains to be divided into four zones : (i) Bhabhar, (ii) Tarai, (iii) Bangar and (iv) Khadar.
