A Correct answer
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

  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'

It's a non-renewable resource.

  1. Water

  2. Solar energy

  3. Coal

  4. Soil
Reveal answer Fill a bubble to check yourself
C Correct answer
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?

  1. Deforestation

  2. Reducing the use of vehicles

  3. The burning of the wastage

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

Afforestation involves planting trees, which helps in water conservation by reducing runoff, increasing groundwater recharge, and maintaining the water cycle. Deforestation and burning waste are harmful to the environment.

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


  1. Oil

  2. Coke

  3. Nuclear energy

  4. Other organic substance
Reveal answer Fill a bubble to check yourself
C Correct answer
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.
