This plain is formed by three river system , The Indus , The Ganga and The Brahmaputra , along with their tributaries . This plain is formed by alluvial soil . It spreads over an area of 7 lakh sq. km. These plains are about 2400 km long and between 240 and 320 km broad.

They are densely populated due to the fertile soil , adequate water supply , favourable climate and terrain .

The rivers originating from the northern plain flows through the mountain and lastly deposit the minerals and silt . This is why Northern plain have a very fertile soil.

The Indian Deserts :-

This lies on the western margins of tha Aravalli hills . It consists of wave like sandy plains with various types of sand dunes also. It receives less than 150 mm rainfall annually . It has a arid climate with low vegetation due to this . Here streams only appear during the monsoon season . Lungi is the large river basin in this reason.

Crescent shaped sand dunes called branches cover most of this deserts , but Longitudinal dunes are also seen on the western edge of this region near the Indo-Pakistan border . This desert is known as Thar desert.
