- Chotanagpur plateau represents the north- eastern projection of the Indian Peninsula.
- Mostly in Jharkhand, the northern part of Chhattisgarh and Purulia district of West Bengal.
- The Son River flows in the north-west of the plateau and joins the Ganga.
- This plateau is composed mainly of Gondwana rocks.
- The plateau is drained by numerous rivers and streams in different directions and presents a radial drainage pattern.
- Rivers like the Damodar, the Subarnrekha, the North Koel, the South Koel and the Barkar have developed extensive drainage basins.
- The Damodar river flows through the middle of this region in a rift valley from west to east. Gondwana coal fields which provide the bulk of coal in India are situated here.
- North of the Damodar river is the Hazaribagh plateau with an average elevation of 600 m above mean sea level. This plateau has isolated hills. It looks like a peneplain due to large scale erosion.
- The Ranchi Plateau to the south of the Damodar Valley rises to about 600 m above mean sea level. Most of the surface is rolling where the city of Ranchi (661 m) is located.
- The Rajmahal Hills forming the northeastern edge of the Chotanagpur Plateau are mostly made of basalt and are covered by lava flows.
