  • Question 1
    1 / -0

    Which of the following natural resources is exhaustible?

    Solution

    Coal is a natural resource. Coal is found in limited quantities and its amount is depleting. It cannot be replenished and therefore coal is an exhaustible natural resource.

    The correct answer is B.

  • Question 2
    1 / -0

    Which of the following statements about fossil fuels is correct?

    Solution

    Many substances are obtained from petroleum and natural gas. Some of these products are fertilizers, detergents, fibres, nylon, polythene etc. These products are together called petrochemicals.

    The correct answer is D.

  • Question 3
    1 / -0

    Use the following information to answer the next question.

    Consider the following statements regarding fossil fuels.

    I Fossil fuels are the dead remains of living organisms that have been buried for a long time.

    II Excessive use of fossil fuels causes global warming and a depletion of natural resources.

    III Earthquakes occur as a result of burning fossil fuels.

    Among the given statements,

    Solution

    Coal, petroleum, natural gas, etc. are fossil fuels. These are formed from the remains of dead organisms that were buried under the Earth’s crust over millions of years ago. Hence, statement I is correct.

    Fossil fuels are exhaustible natural resources because these are found in limited amounts. Excess use of fossil fuels causes global warming and depletion of these resources. Hence, statement II is correct.

    Earthquake is a natural phenomenon that is caused by the movement of tectonic plates under the Earth’s crust. It is not caused by excess use/burning of fossil fuels. Hence, statement III is incorrect.

    The correct answer is C.

  • Question 4
    1 / -0

    Which alternative incorrectly classifies a natural resource on the basis of its availability?

    Solution

    Petroleum is not an inexhaustible resource. The reserves of petroleum on Earth are limited; therefore it is an exhaustible resource.

    The correct answer is C.

  • Question 5
    1 / -0

    Carbonization is a

    Solution

    The process through which coal is formed is called carbonization. It is a slow process during which the dead vegetation such as trees and plants are converted into coal under very high temperature and pressure.

    The correct answer is B.

  • Question 6
    1 / -0

    Use the following information to answer the next question.

    Consider the following statements related to petroleum.

    I. It is formed from the remains of dead sea organisms.

    II. It is formed from the remains of dead land organisms.

    III. It is formed under low pressure and temperature.

    Among the given statements,

    Solution

    Petroleum is obtained from dead organisms living under the sea. These organisms settle at the bottom of the sea. Over the course of time, many layers of sand got deposited over these dead organisms. Under conditions of high pressure and temperature, these got converted into petroleum.

    The compression of organic matter comprising plants and other vegetation on land, under conditions of high pressure and temperature over a period of millions of years, led to the formation of coal.

    Therefore, statement I is true while statements II and III are false.

    The correct answer is A.

  • Question 7
    1 / -0

    The correct answer is B.

  • Question 8
    1 / -0

    Use the following information to answer the next question.

    Inside the Earth, deposits of not only water, but also oil and gas are found.

    The order in which the given substances will be found if a tunnel is drilled into the Earth is

    Solution

    Deposits of natural gas are found above the deposits of oil since gas is lighter than oil. Similarly, deposits of oil are found above the deposits of water because oil is lighter than water. If a tunnel is drilled into the Earth, then the deposits will be obtained in the order-gas, oil and water respectively.

    The correct answer is A.

  • Question 9
    1 / -0

    Which alternative does not pair a component of petroleum with its use?

    Solution

    Paraffin wax is a constituent of petroleum. It is used in the manufacturing of ointments, candles, petroleum jelly, etc. It is not used in the surfacing of roads. Bitumen, a petroleum constituent, is used in road surfacing.

    The correct answer is D.

  • Question 10
