Which of the following are the conventional sources of energy?

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

  1. Wood, dung-cakes, coal, kerosene,

  2. diesel, electricity

  3. LPG, petrol, CNG,

  4. all of them

Show answer
Correct Option: D
Explanation:

Conventional energy sources includes oil, gas and coal. These conventional sources are usually fossil fuels. Their use leads to increased greenhouse gas emissions and other environmental damage.These sources of energy are also called non renewable sources. These sources of energy are in limited quantity except hydro-electric power. These include commercial (coal, petroleum, electricity etc..) and non-commercial (fire wood, straw, dried dung etc.. ).

Which of the following can not be taken to conserve energy resources (like coal and petroleum)?

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

  1. Use stairs to climb at least up to three floors of a building instead of taking a lift. This will save electricity.

  2. Pressure cookers should not used for cooking food as the food cooked in cooker at very high pressure, in steam is harmful.

  3. Solar cookers should be used to cook food whenever possible.

  4. The use of biogas as domestic fuel should be encouraged in rural areas.

Show answer
Correct Option: B
Explanation:

There are many ways to conserve energy resources like coal or petroleum.

(i) Using stairs instead of lift for general purpose.
(ii) Biogas should be used in rural areas as cowdung is available.
(iii) Solar panels should be used wherever possible.

State the reasons for resources, why they are finishing rapidly?

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

  1. Increase in population

  2. Increase in consumption of fuel

  3. Increase in plantation

  4. All of the above

Show answer
Correct Option: A,B
Explanation:

A .Because of the population explosion (rapid increase in population) in the world with limited resources, our natural resources are depleting.

B. With increased population growth, comes an increasing demand for fuel consumption, which is rapidly decreasing fossil fuel resources. 
C. Instead of planting trees, deforestation is taking place to make a way for the development of cities and industries. 
Hence, only A and B are correct.

The materials which are finishing fastly are ________.

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

  1. non-renewable

  2. renewable

  3. both a and b

  4. none of these

Show answer
Correct Option: A
Explanation:

Non-renewable resources such as coal, petroleum and natural gas are finishing fastly due to increase in population and industrialisation which results in increased demands of these resources. A non renewable resources is a resources of economic value that cannot be readily replaced by natural means on a level equal to its consumption. 

Which kind of materials (resources) can be extinct in future?

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

  1. Non-renewable

  2. Renewable

  3. Both $A$ and $B$

  4. None of these

Show answer
Correct Option: A
Explanation:

Non-renewable resources take millions of year to get replenished. So it can extinct in the near future.

Most fossil fuels, such as oil, natural gas and coal are considered non-renewable resources in that their use is not sustainable because their formation takes billions of years.

Hence, the correct option is $\text{A}$

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.
