Explanation:
The Northern Plains are formed of alluvial soil. The deposition of alluvium in a vast basin lying at the foothills of the Himalayas over millions of years, formed this fertile plain.

The northern plain is formed by the Indus, the Ganga, the Brahmaputra and their tributaries. These rivers divide it into three river basins ( a basin is a region drained by a river and its tributaries). ... It is drained by the rivers Yamuna, Ganga, Ghaghara, Gandak, Kosi and Teesta from the Himalayas in the north.
