evs how to save fuel define fossil fuels conservation of fuels reason for finishing of materials (resources) fuel and conservation

  1. Exhaustible : petroleum, coal, natural gas, forests, minerals, water

    Inexhaustible : wind, sunlight

  2. Exhaustible : petroleum, coal, natural gas, forests, minerals.

    Inexhaustible : wind, sunlight, water.

  3. Exhaustible : petroleum, coal, natural gas, forests, wind

    Inexhaustible : sunlight, water, minerals

  4. Exhaustible : petroleum, coal, natural gas, forests, minerals, wind

    Inexhaustible : sunlight, water.

Show answer
Correct Option: B
Explanation:

An inexhaustible resource is one that is replaceable, while an exhaustible resource is not replaceable, hence wind, sunlight and water are inexhaustible resources while other are exhaustible resources.

What is the cause of a very high demand of water even though it is inexhaustible natural resource?

evs how to save fuel define fossil fuels conservation of fuels reason for finishing of materials (resources) fuel and conservation

  1. Fresh water makes only small volume of world's water

  2. Most of the fresh water is in the form of ice and snow cover

  3. Conversion of sea water to fresh water is difficult and not economical

  4. All of the above

Show answer
Correct Option: D
Explanation:

Water is inexhaustible natural resource .i.e. it is never going to deplete but it has a very high demand because the large percentage of water which is present on the Earth surface is not suitable for drinking. The suitable form is in the frozen form (ice, snow, glaciers etc). Its conversion to drinking water is non-economical and hence is not favoured.

Which of the following is a resource that does not grow and come back, or a resource that would take a very long time to come back?

evs how to save fuel define fossil fuels conservation of fuels reason for finishing of materials (resources) fuel and conservation

  1. Renewable

  2. Non-renewable

  3. Both a and b

  4. None of above

Show answer
Correct Option: B
Explanation:

A natural resource is anything that people can use which comes from nature. People do not make natural resources, but gather them from the earth. A non-renewable resource is a resource that does not grow and come back or a resource that would take a very long time to come back. For example, coal is a non-renewable resource. 

Which of the following non-renewable resource can be reused by recycling?

evs how to save fuel define fossil fuels conservation of fuels reason for finishing of materials (resources) fuel and conservation

  1. Coal

  2. Metallic minerals

  3. Petroleum

  4. None of above

Show answer
Correct Option: B
Explanation:

Non-renewable resources form extremely slowly or do not naturally form in the environment. Of the non-renewable resources, metallic minerals can be reused by recycling, but coal and petroleum cannot be recycled.

What is the function of PCRA?

  1. Advises people to save petrol/diesel

  2. Advises people to prevent water pollution

  3. Petroleum Refining Industry

  4. None of above

Show answer
Correct Option: A
Explanation:

In India, the Petroleum Conservation Research Association(PCRA) advises people how to save petrol/diesel while driving. 

Which of the following is a non-renewable resource?

evs how to save fuel define fossil fuels conservation of fuels reason for finishing of materials (resources) fuel and conservation

  1. Tidal energy

  2. Wind

  3. Petroleum

  4. Solar energy

Show answer
Correct Option: C
Explanation:

A non-renewable resource does not renew itself at a sufficient rate for sustainable economic extraction in meaningful human time-frames. Earth minerals, metal ores, fossil fuels and groundwater in certain aquifers are all non-renewable resources.
In contrast, resources such as timber and wind (used to power energy conversion systems) are considered renewable resources.

Among following which can be said to be as causes of energy crisis?

evs how to save fuel define fossil fuels conservation of fuels reason for finishing of materials (resources) fuel and conservation

  1. Unexplored Renewable Energy Options

  2. Delay in Commissioning of Power Plants

  3. Wastage of Energy

  4. All of the above

Show answer
Correct Option: D
Explanation:

Energy crisis is any significant bottleneck in supply of energy resources to an economy. It occurs generally by-

(i) Wastage of energy
(ii) Delay in commisioning of power plants
(iii) Unexplored renewable options
(iv) More use of electricity

Why is water a renewable resource?

evs how to save fuel define fossil fuels conservation of fuels reason for finishing of materials (resources) fuel and conservation

  1. Water continuously evaporates.

  2. Man can create water.

  3. Use of water is minimum.

  4. The above statement is incorrect.

Show answer
Correct Option: A
Explanation:

A renewable resource is any natural resource that replaces itself given enough time. The rate of replenishment must be equal to or faster than the rate of usage. As water continuously evaporates from the Earth's surface, it collects in the atmosphere to later come back to the Earth as rain. On the Earth itself surface water replenishes groundwater, and groundwater replaces surface water. With careful management and responsible usage, water is a renewable resource.

Which of the following measure can be taken to preserve natural resources?

evs how to save fuel define fossil fuels conservation of fuels reason for finishing of materials (resources) fuel and conservation

  1. Switch off electricity when not required

  2. Car pooling

  3. Both $A$ and $B$

  4. Use Petrol instead of CNG

Show answer
Correct Option: C
Explanation:

Natural resources should be used wisely because most of them are exhaustible and cannot be replenished or take million years to replenish. CNG is the cleanest fuel and hence should be used instead of petrol. People should also adopt car pooling to prevent excessive use of fuel and also protect from pollution.
