Question

In which type of rock coal is found?
 (A) Igneous rock
 (B) Metamorphic rock
 (C) Sedimentary rock
 (D) Sand stone

Answer 1

Hint Coal is a black or dark brown rock that can be burned for fuel and used to generate electricity. It contains a lot of carbon and hydrocarbons, which contain energy that can be released by fire (heat).

Complete step by step Answer
Coal undergoes physical and chemical changes as a result of rising temperatures, and sometimes there is a misconception that coal is a metamorphic rock.
It contains locally collected and transported raw materials. Coal is a highly combustible material, composed mainly of hydrocarbons, obtained in the form of stones and can be used as heat or light fuel or both. It is formed when composite plants remain under high pressure for a long time. Coal is made from the delicate materials of plants, and it undergoes many changes before it becomes the standard black and glossy substance burned as fuel.

Additional Information Coal is a mountain rock. Coal is converted by biological processes and thermal burial processes at various stages. The most important element in coal is humus. Coal ships are available on every continent. The largest coal mines are located in the United States, Russia, China, Australia and India. Coal is found in beds, called stitches, which are a coin that resembles a blanket that measures a few inches to a few feet or a few hundred feet in diameter.

The correct answer is option (C) Sedimentary rock

Note
 Coal is the world's largest energy source, as well as fossil fuels. It contains a lot of carbon and hydrocarbons, which contain energy that can be released by fire (heat).
