What is north indian plains?
The Indo-Gangetic Plain also known as the Northern plains and the North Indian River Plain is a large and fertile plain encompassing most of northern and eastern India, the most populous parts of Pakistan, and virtually all of Bangladesh. The region is named after the Indus and the Ganges, the twin river systems that drain it. The Indo-Gangetic plain is bound on the north by the abruptly rising Himalayas, which feed its numerous rivers and are the source of the fertile alluvium deposited across the region by the two river systems. The southern edge of the plain is marked by the Vindhya- and Satpura Range, and the Chota Nagpur Plateau. On the west rises the Iranian Plateau.
