Previous Year Questions (PYQs)
Prelims
Q. Which one of the following is the appropriate reason for considering the Gondwana rocks as most important of rock systems of India? (CSE Prelims 2010) (a) More than 90% of limestone reserves of India are found in them (b) More than 90% of India's coal reserves are found in them (c) More than 90% of fertile black cotton soils are spread over them (d) None of the reasons given above is appropriate in this context Answer: (b) -- Gondwana rock systems contain nearly 98% of India's total coal reserves. These coal deposits are found in the Damodar valley (Jharkhand-West Bengal), Mahanadi valley (Chhattisgarh-Odisha), Son valley (Madhya Pradesh), and Godavari-Wardha valley (Maharashtra-Andhra Pradesh).
Q. Despite having large reserves of coal, why does India import millions of tonnes of coal? (CSE Prelims 2012)
- It is the policy of India to save its own coal reserves for future, and import it from other countries for the present use.
- Most of the power plants in India are coal-based and they are not able to get sufficient supplies of coal from within the country.
- Steel companies need coking coal for their smelters and most of the coalfields in India do not produce coking coal. (a) 1 only (b) 2 and 3 only (c) 1 and 3 only (d) 1, 2 and 3 Answer: (b) -- Statement 1 is incorrect as India has no such policy of conserving domestic reserves. Statements 2 and 3 are correct. India's thermal power plants face supply gaps, and Indian coalfields predominantly produce non-coking coal, while steel plants require coking coal that must be imported.
Q. With reference to two non-conventional energy sources called 'coalbed methane' and 'shale gas', consider the following statements: (CSE Prelims 2014)
- Coalbed methane is the pure methane gas extracted from coal seams, while shale gas is a mixture of propane and butane only that can be extracted from fine-grained sedimentary rocks.
- In India, abundant coalbed methane sources exist, but so far no shale gas sources have been found. (a) 1 only (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2 Answer: (d) -- Statement 1 is incorrect because coalbed methane is not pure methane (it contains nitrogen, CO2, and other hydrocarbons), and shale gas is predominantly methane, not a mixture of propane and butane. Statement 2 is incorrect because India has identified six basins for shale gas exploration, including Cambay, Assam-Arakan, Gondwana, KG onshore, Cauvery, and Indo-Gangetic basins.
Q. With reference to solar water pumps, consider the following statements: (CSE Prelims 2020)
- Solar power can be used for running surface pumps and not for submersible pumps.
- Solar power can be used for running centrifugal pumps and not the ones with piston. (a) 1 only (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2 Answer: (d) -- Both statements are incorrect. Solar power can run both surface and submersible pumps. Submersible solar pumps are widely used for deep wells and boreholes. Solar power can also run piston (positive displacement) pumps, diaphragm pumps, and helical rotor pumps, not just centrifugal pumps.
