Questions Related to conservation of fuels

What happen when oil is disappeared from earth?

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

  1. Car stopped running

  2. Bikes stopped running

  3. Aeroplane stopped running

  4. All of the above

Show answer
Correct Option: D
Explanation:

Cars, bikes and aeroplanes are operating on petrol, diesel and kerosene, which are extracted from oil. If they disappear on earth, all of them stop running.

Among the following pick the correct way of conserving natural resources.

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

  1. Rainwater harvesting

  2. Stop throwing material in river

  3. Stop deforestation

  4. Stop using polythene

Show answer
Correct Option: A,C
Explanation:

A . Rainwater harvesting is the method of collection and storage of rainwater in natural reservoirs or tank and infiltration of surface water into subsurface aquifers (like well or underground water pumped through hand pump). This method is used to conserve drinking water (a natural resource).

B. This is the way of stopping the pollution of rivers and not a conservation method.
C. The banning of cutting of trees will conserve the natural resources like soil, air and wood. It is a method of preventing global warming, landslides, etc.
D. Again, banning of the usage of poly-bags can prevent solid waste pollution. This is not a conservation method.

Using __________ is secondary reason for finishing materials ( resources ) fastly.

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

  1. instruments

  2. vehicles

  3. both a and b

  4. none of these

Show answer
Correct Option: B
Explanation:

B, Vehicles are secondary reasons for finishing resources as number of vehicles are increasing day by day which results in great demand of fuels. 

To conserve materials (resources), it is necessary to use them in ________.

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

  1. limited amount

  2. unlimited amount

  3. both a and b

  4. none of these

Show answer
Correct Option: A
Explanation:

To conserve materials, it is necessary to use them in the limited amount. We need  to use it judiciously for sustainable development. We need to conserve our natural resources because it is the main source of our daily needs. We need to conserve it because they are limited only. And if these resources are abused and harmed, we will have short quantity of sources for food and living.

Why should we conserve biodiversity?

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

  1. We should preserve the biodiversity we have inherited

  2. A loss of diversity may lead to a loss of ecological stability

  3. Both (a) and (b)

  4. None of the above

Show answer
Correct Option: B
Explanation:

A loss of biodiversity will result in loss of ecological balance. Biodiversity is an integral part of our environment. 

Biodiversity is necessary for our existence as well as valuable in its own right. This is because it provides the fundamental building blocks for the many goods and services which provides a healthy environment to lead our life.

Hence, the correct option is $B$

If materials will be finished, people will struggle for __________.

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

  1. electricity

  2. rain

  3. water

  4. none of these

Show answer
Correct Option: A
Explanation:

The correct option is A if materials will be finished then people will struggle for electricity as it is produced by using coal in the thermal power plant. 


Coal is a fossil fuel which is formed from the accumulated remains of living organisms that were buried millions of years ago. 

Pressure, heat and time allow the organic matter to transform into one of the three major types of fossils fuel, which are coal, oil and natural gas.


Hence, the correct option is A.

Inexhaustible resources are:

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

  1. not going to finish

  2. will finish

  3. will renewed

  4. None of these

Show answer
Correct Option: A
Explanation:
A, Inexhaustible resources  are the resources which cannot be finished by human activities such as soil, water and sunlight. 
An inexhaustible resource is a resource that never runs out or gets depleted. Some of such resources include wind, sun, solar energy, tides, and geothermal energy. They are mostly the natural occurring resources hence they reappear naturally.

Industrial boom, increased population and wastage are the causes of _________.

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

  1. water depletion

  2. oil depletion

  3. coal depletion

  4. None of these

Show answer
Correct Option: B

_____ is a method of conservation of water.

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

  1. Rainwater harvesting

  2. Rainwater dropping

  3. Rain planning

  4. None of these

Show answer
Correct Option: A
Explanation:

Rainwater harvesting is the accumulation and storage of rainwater for reuse on-site, rather than allowing it to run off. Rainwater can be collected from rivers or roofs, and in many places, the water collected is redirected to a deep pit, a reservoir with percolation. Its uses include water for gardens, livestock, irrigation, domestic use with proper treatment, indoor heating for houses, groundwater harvesting.

Cooking food by covering, is the method to save _________.

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

  1. LPG

  2. CNG

  3. BNG

  4. None of these

Show answer
Correct Option: A
Explanation:

Covering pans keeps the heat in the pan, cooking the food. 


I’ve seen estimates that covered pans consume less than half the energy of uncovered ones, so this is a huge saving both in the amount of LPG used and the heat released in the cabin is used for cooking the food faster.

Hence the option A is correct.
