Minerals and energy resources of India MCQ - Practice Questions with Answers

India's metallic mineral distribution is tied to geology. Old hard-rock regions of the Peninsular Plateau have exposed, folded, fractured and weathered crystalline and metamorphic rocks, so areas such as Chotanagpur, Odisha, Chhattisgarh, Karnataka and parts of Rajasthan recur in mineral questions. By contrast, the Northern Plain is fertile because of alluvium and is mainly an agricultural region. Therefore, the correct map rule is that alluvial plains are not the chief metallic-mineral base.

Renewable energy is not treated as a simple, problem-free target. Solar energy is linked with sunshine, open land, transmission lines and storage. Rajasthan, Gujarat and parts of peninsular India are important because dry climate, open land and high solar radiation support large projects. At the same time, grid connection, desert ecology, land use, dust, cleaning water, local grazing and livelihood concerns. Therefore solar energy clearly depends on practical conditions, while the claim of no land-use, grid or storage concerns is false.

There is a direct functional split for coal resources. Coking coal supports iron and steel production, which is why Jharia is strongly associated with steel. Thermal coal supports electricity generation through coal-based power. Lignite is a lower-grade brown coal and belongs with regional thermal energy in selected basins such as Neyveli and parts of western Rajasthan. This makes the sequence coking coal to steel, thermal coal to power, and lignite to regional thermal energy.

There is a clear map rule: most metallic minerals occur in the old hard-rock regions of the Peninsular Plateau. These crystalline and metamorphic rocks have been exposed, folded, fractured and weathered over a very long time. That is why Chotanagpur, Odisha, Chhattisgarh, Karnataka, eastern Maharashtra and parts of Rajasthan repeatedly appear in mineral questions. The Northern Plain is mainly alluvial and agricultural, while coastal placer zones and desert sedimentary basins explain different resources.

There is a key distinction: petroleum is studied through sedimentary basins, not through hard-rock mineral belts like iron ore or bauxite. They explain the reason as well. Hydrocarbons need source rocks, reservoir rocks and geological traps so that petroleum and natural gas can form and collect. Assam, Mumbai High, Cambay, Krishna-Godavari, Cauvery and Barmer-Sanchore are examples of this basin-based map. Thus the assertion is true, the reason is true, and the reason explains the assertion.
