  1. Storing water

  2. Storing light

  3. Storing sun rays as energy source

  4. None of the above

Show answer
Correct Option: C
Explanation:

The device which can trap the solar energy and convert the solar energy into an electrical form of energy is called as the solar cell. Solar cells are generally used for the storage of the radiations from the sun in the form of energy resource. These cells are used in the solar panels for the generation of electricity for the street lights. 

Thus, the correct answer is option C. 

Thermal pollution in water bodies is caused due to discharge of

commercial applications management of natural resources unequal distribution of resources protecting our environment rules are for everyone

  1. Waste from agricultural fields

  2. Hot water from power plants

  3. Hot chemicals from industries

  4. Waste from mines

Show answer
Correct Option: B
Explanation:

Thermal pollution is caused by change in water temperature which leads to degradation of water quality. It is caused due to use of water as a coolant by power plants and industrial manufacturers. When such water is returned to the natural environment at a higher temperature, it decreases oxygen supply and affects ecosystem composition.

So, the correct answer is option B.
