Select the non renewable resources from the following

  1. Forest

  2. Soil

  3. Water

  4. Fossil fuels
Reveal answer Fill a bubble to check yourself
D Correct answer
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 alternative energy source has the least long-term impact on the environment?
I.    Solar power
II.  Wind power
III. Nuclear power

  1. I only

  2. II only

  3. III only

  4. I and II only

  5. II and III only
Reveal answer Fill a bubble to check yourself
D Correct answer
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'
