Which one of the following is an non-conventional source of energy?

  1. Hydroelectric energy

  2. Biomass energy

  3. Solar pond

  4. Fossil fuel energy
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • Solar pond is a non-conventional source of energy, which is renewable or inexhaustible and do not cause environment pollution. More over they do not require heavy expenditure. Energy generated by using wind, tides, solar geothermal heat are also non-conventional energy sources.
  • Hydroelectric energy, biomass energy and fossil fuel energy are conventional sources of energy, since they are non-renewable or exhaustible and cause environmental pollution. 
  • So the correct answer is 'Solar pond'.

Which one is a non-renewable energy resource?

  1. Hydropower

  2. Tidal power

  3. Geothermal power

  4. Nuclear energy
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Non-renewable energy resource is a resource that is limited in quantity. It cannot be recycled or replenished. The examples include coal, petroleum, natural gas, nuclear energy. The renewable energy resources include hydropower (wind), tidal power (water), geothermal power (solar energy).

Thus, the correct answer is 'Nuclear energy.'

Which of the following is not a renewable source of energy?

  1. Coal

  2. Wood

  3. Cow dung

  4. Agriculture waste
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Non-renewable energy sources are those that cannot be reused again as their actual form gets converted to a waste product or some other non-usable form. Coal is obtained from the Earth's crust by the decomposition of dead matter for long period of time. It is commonly used as the source of energy. There are limited deposits of coal and it takes a long time to be formed. Hence it is a non-renewable form of energy.  Thus the correct answer is option D.

Hydropower is

  1. Inexhaustible and renewable resource

  2. Inexhaustible and nonrenewable resource

  3. Exhaustible and nonrenewable resource

  4. Exhaustible and renewable resource
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Hydropower is a method of generating power by flowing water, which spins the turbines, it is a renewable source of energy and also it is inexhaustible

So, the correct answer is 'Inexhaustible and renewable resource'

Coal and petroleum are non-renewable inexhaustible resource.

  1. True

  2. False

  3. Nither

  4. Either
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Coal and petroleum are non-renewable exhaustible natural resources as once used they are lost forever. They are not replenished by nature and their formation takes a very long period of time. 

On the other hand, inexhaustible resources are renewable resources that get replenished by nature and hence, they don't get depleted when used. For example, forests, water etc.
Hence the statement given in the question is not correct.
So, the correct answer is 'False'.

Mineral and metals are 

  1. Biodegradable resources

  2. Renewable

  3. Non- renewable

  4. Renewable and non - renewable resources
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Minerals and metals are non renewable sources of energy as depletion in it is not possible to renew again.

Thus, the correct answer is 'Non - renewable.'

The fossil fuels, coal and petroleum, will ultimately be exhauste.

  1. True

  2. False

  3. Nither

  4. Either
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
The fossil fuels, coal and petroleum will ultimately exhaust because these are non-renewable natural resources. They are not replenished by nature and once used, they are lost forever. It takes a very long time for their formation. Petroleum is produced from crude oil which takes million of years to form in the earth from the dead remains of plants and animals. Similarly, coal and fossil fuels also form in this way in million of years. Hence, they will ultimately get exhausted as the demand for these resources is increasing.
Hence, the statement given in the question is correct.
So, the correct answer is 'True'.
