INDIAN GEOGRAPHY

Detailed explanation-1: -Black soil is abundant in the Deccan plateau region. One of the distinct features of the Peninsular plateau is the black soil area known as Deccan Trap. This is of volcanic origin, hence, the rocks are igneous. Actually, these rocks have denuded over time and are responsible for the formation of black soil.

Detailed explanation-2: -It consists of numerous layers of solidified flood basalt that together are more than about 2, 000 metres (6, 600 ft) thick, cover an area of about 500, 000 square kilometres (200, 000 sq mi), and have a volume of about 1, 000, 000 cubic kilometres (200, 000 cu mi).

Detailed explanation-3: -These soils are named as black cotton soil as it is famous for the purpose of cultivation of cotton. Black soil or black cotton soil are formed from the Deccan Trap rocks known as Zonal Soils. Black cotton soil is mostly found in the Deccan trap region.

Detailed explanation-4: -Black soil is also called as regur soil or black cotton soil. It is the third major group of soil in India and forms the top part of the earth’s surface, that includes disintegrated rock, humus, inorganic, and organic materials. The soil is in black colour and is formed by the weathering of igneous rock.
