Explanation:

Chotanagpur Plateau

? Chotanagpur plateau represents the north-eastern projection of the Indian Peninsula.

? Option (d) is the correct answer. It is extended mostly in Jharkhand, 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.

? The average elevation of the plateau is 700 m above sea level.?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. {Drainage Pattern}

? Rivers like Damodar, the Subarnarekha, 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. Here are found the Gondwana coal fields which provide bulk of coal in India.

? 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.

? At places it is interrupted by monadnocks (an isolated hill or ridge of erosion-resistant rock rising above a peneplain. Ex: Ayers Rock in Australia) and conical hills.

? The Rajmahal Hills forming the north eastern edge of the Chotanagpur Plateau are mostly made of basalt and are covered by lava flows {Basaltic Lava}.

? They run in a north-south direction and rise to average elevation of 400 m (highest mount is 567 m). These hills have been dissected into separate plateaus.
