- The plain spreads over the northern states of Haryana, Delhi, U.P., Bihar and partly Jharkhand.
- The Ganga plains also extend towards Bengal towards the eastern region.
- Further towards the east, in Assam lies the Brahmaputra plain.
- The northern plains are called as flatlands with no variations in its relief. However, this is not completely true. These vast plains also have diverse relief features.
