Question

Which plateau is the mineral heart in India?
A) Chota Nagpur plateau
B) Bhander plateau
C) Tibetian plateau
D) Malwa plateau

Answer 1

Hint: A plateau, also known as a high plain or a tableland, is an area of a highland consisting of flat terrain that is raised sharply above the surrounding area on at least one side in geology and physical geography. Deep hills can often be found on one or more sides.

Complete answer:
A mineral or mineral species is a solid chemical substance with generally well-defined chemical composition and a particular crystal structure that occurs naturally in pure form in geology and mineralogy. Compounds found solely in living organisms are usually excluded from the geological definition of mineral. However, certain minerals (such as calcite) are biogenic or are organic molecules in the sense of chemistry (such as mellite). In addition, living organisms frequently produce inorganic
minerals (such as hydroxyapatite), which are also found in rocks.

The Chota Nagpur Plateau is a plateau in eastern India that encompasses much of the state of Jharkhand, as well as sections of Bihar, Odisha, West Bengal, and Chhattisgarh. To the north and east of the plateau is the Indo-Gangetic Plain, while to the south is the Mahanadi river basin. The Chota Nagpur Plateau covers roughly 65,000 square kilometres in total (25,000 sq mi).

The Chota Nagpur Plateau is a continental plateau, which is a large expanse of land that rises above the surrounding terrain. The plateau was created by continental uplift caused by forces deep inside the earth. The plateau's ancient origin may be seen in the Gondwana substrates.

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 centre basin has massive coal reserves that cover 2,883 square kilometres (1,113 sq mi). Jharia, Raniganj, West Bokaro, East Bokaro, Ramgarh, South Karanpura, and North Karanpura are the basin's major coalfields.

Therefore the correct answer is option ‘A’.

Note: The Tibetan Plateau, also known as the "Roof of the World," is the world's largest and highest plateau, which is still being formed by the collisions of the Indo-Australian and Eurasian tectonic plates. At about 5,000 meters (16,000 feet) above sea level, the Tibetan plateau covers approximately 2,500,000 km2 (970,000 sq mi).
