Question

how are northern plains india formed "how are they categorized"

Answer 1

Hey Mate,

The northern plains stretch between the Himalayas and the Peninsular Plateau.This plain is formed by the deposition of alluvium ( a deposit of clay, silt, and sand left by flowing floodwater in a river valley or delta, typically producing fertile soil ) brought by the rivers from the Himalayan and the plateau. This plain is mainly developed by rivers Ganga, Indus and Brahmaputra. The fine and the deep alluvium deposits by the rivers make the northern plains one of the most fertile plains in the world.

Hope it helps you!
