Question

Coal and Petroleum are examples of ________.
A. Fossil Fuels
B. Non-renewable resources
C. Fuel minerals
D. All of these

Answer 1

Hint:There are some resources which are formed from dead remains of plants and animals, can be used as fuels in households, factories, industries and get exhausted once used and take millions of years to replenish back as they are present in limited quantities.

Complete answer:
Coal and petroleum exhibit all the given properties, that is, they are fossil fuels, non-renewable resources and are also fuel minerals. The term fossil fuel is used for the buried deposits of organic materials which are formed from the decay and decomposition of plants and animals which eventually get converted into coal, crude oil, natural gas due to extreme heat and pressure in the crust of the earth taking hundreds to millions of years. Non-renewable resources are those resources which cannot or are very difficult to renew in nature once they are being used. Fuel minerals are those minerals which are used as fuels for domestic purposes. Coal and petroleum have all these properties, that is, they are fossil fuels as they are formed from remains of plants and animals. They are non-renewable resources as they are present in limited quantities and take millions of years to get renewed in nature once used. They are also fuel minerals as they are used for combustion, heating, running machines and automobiles, generating electricity.

Hence, the correct answer is option (D).

Note:Although both coal and petroleum are used in daily life in houses, factories, and industries, coal is preferred over petroleum because coal releases less harmful by-products into the atmosphere on burning unlike petroleum, which releases comparatively more harmful by-products.
