Question

Why northern plains are also called depositional plains

Answer 1

It is so because the rivers Ganga, Indus, and Brahmaputra, while moving downward from the Himalayas, erode the river banks and carry silt along, later depositing it further in the northern plains.

Answer 2

northern plains are called depositional plains because the plains were formed by deposits of three rivers and their tributaries these 3 deposits are now the fertile deposits so they are called depositional plains
