Question

Mining occupation is well developed on the Chhota Nagpur plateau because of ______.
A) road transport
B) availability of minerals
C) generation of employment
D) labour supply

Answer 1

Hint: The Chota Nagpur Plateau received its name from the 'Nagwanshi,' who ruled the area for a long time, and 'Chota,' which means small,' from a village called Chota on the outskirts of Ranchi, where an old fort of the Nagvansh Is ruler still exists.

Complete answer:
The Chota Nagpur Plateau is a continental plateau, which is a large area of land that rises above the surrounding terrain. The plateau was created by continental uplift caused by forces deep within the earth. The broad plateau is split into a number of smaller plateaux or sub plateaus.

Mica, bauxite, copper, limestone, iron ore, and coal are all found in abundance on the Chota Nagpur plateau. The Damodar valley is rich in coal and is considered the country's primary source of coking coal. The central basin contains massive coal reserves that cover 2,883 square kilometres. and other important coalfields in the basin are Jharia, Raniganj, and West Bokaro.

Factors like road transport, employment and labour supply started developing only when mining started in these regions. Hence, these factors are not responsible for the development of chhota Nagpur plateau. Option A, C and D are incorrect.

The correct answer is (B) availability of minerals.

Note: The Chota Nagpur Plateau is a plateau in eastern India that encompasses most of the state of Jharkhand, as well as portions of Odisha, West Bengal, and Chhattisgarh. To the north and east of the plateau is the Indo-Gangetic plain, and to the south is the Mahanadi river delta.
