Questions Related to promotion of renewable resources

Select the non renewable resources from the following

commercial applications water and air and their importance natural resources and their types promotion of renewable resources protecting our environment

  1. Forest

  2. Soil

  3. Water

  4. Fossil fuels

Show answer
Correct Option: D
Explanation:

Forests, soil and water are renewable resources because they are replaced naturally and hence can be repeatedly used.

Fossil fuels are obtained by the action of the environment on the dead plants and animals for hundreds of years. They are non renewable because they cannot be reused again as their actual form gets converted to a waste product or some other non-usable form.
Thus the correct answer is option D.

Which of the following is a non-renewable energy resource?

commercial applications water and air and their importance natural resources and their types promotion of renewable resources protecting our environment

  1. Solar

  2. Methane

  3. Hydroelectric

  4. Coal

Show answer
Correct Option: D
Explanation:

An energy source that will run out in future is known as a non-renewable energy resource. Thus coal is a non-renewable energy resource.

Sunlight is ________ natural resource.

commercial applications water and air and their importance natural resources and their types promotion of renewable resources protecting our environment

  1. Inexhaustible

  2. Exhaustible

  3. Both A & B

  4. None of these

Show answer
Correct Option: A
Explanation:

Inexhaustible resource is a natural resource that will never run out so if we take advantage of the greatest  natural resources will not be depleted and will continue to exist, such as water, sunlight, tidal energy, ocean energy and wind energy.

Which alternative energy source has the least long-term impact on the environment?
I.    Solar power
II.  Wind power
III. Nuclear power

commercial applications water and air and their importance natural resources and their types promotion of renewable resources protecting our environment

  1. I only

  2. II only

  3. III only

  4. I and II only

  5. II and III only

Show answer
Correct Option: D
Explanation:
I.   Solar power is the energy generated from solar light i.e. the sunlight.
II.  Wind power is the energy generated by the wind.
III. Nuclear power is the energy generated through nuclear reactions.
Since solar light and wind has no danger and has least impact, so solar power and wind power have the least long-term impact on the environment.
So, the correct answer is 'I and II only'

It's a non-renewable resource.

commercial applications water and air and their importance natural resources and their types promotion of renewable resources protecting our environment

  1. Water

  2. Solar energy

  3. Coal

  4. Soil

Show answer
Correct Option: C
Explanation:
  • There are different types of resources. 
  • The non-renewable forms of resources cannot be replenished again when the source gets exhausted. 
  • The coal is an example of a non-renewable source of energy. 
  • Soil, water, and solar energy are examples of the renewable sources of energy.
  • Thus, the correct answer is option C. 

Water is an essential commodity for survival. What can we do to help increase water resources?

commercial applications water and air and their importance natural resources and their types promotion of renewable resources protecting our environment

  1. Deforestation

  2. Reducing the use of vehicles

  3. The burning of the wastage

  4. Afforestation

Show answer
Correct Option: D

Solar energy is 

commercial applications water and air and their importance natural resources and their types promotion of renewable resources protecting our environment

  1. Cleanest source of energy.

  2. Helpful in photosynthesis.

  3. Renewable source of energy.

  4. All of the above.

Show answer
Correct Option: D
Explanation:

Solar power is energy from the sun that is converted into thermal or electrical energy. Solar energy is the cleanest and most abundant renewable energy source available.
Solar power can be used to generate electricity, it is also used in relatively simple technology to heat water (solar water heaters).

Which is a non-renewable resource?

commercial applications water and air and their importance natural resources and their types promotion of renewable resources protecting our environment

  1. Coal

  2. Petroleum

  3. Natural gas

  4. All the above

Show answer
Correct Option: D

Which of the following is non-renewable?

commercial applications water and air and their importance natural resources and their types promotion of renewable resources protecting our environment

  1. Water

  2. Coal

  3. Forests

  4. Wild life

Show answer
Correct Option: A

Energy source which do not evolve $CO _{2}$


commercial applications water and air and their importance natural resources and their types promotion of renewable resources protecting our environment

  1. Oil

  2. Coke

  3. Nuclear energy

  4. Other organic substance

Show answer
Correct Option: C
Explanation:

The processes for which any CO2 is not evolved is :

  • all the forms of nuclear energy,
  • hydroelectricity (though dam reservoirs in the tropics might free a little methane, which is a greenhouse gas, because of the decaying of biological debris in the water),
  • sun rays,
  • wind,
  • tidal energy,
  • geothermal energy,
  • biomass if replanted.
  • So the correct option is C.
