Solar Energy

1.Does Solar Energy Cause Pollution? Give Reason for Your Answer.

• Solar energy directly provides light and heat energy to us.
• In this process, there is no production of smoke or residue which may cause pollution.

2.Is It Because of the Sun That We Face Hotter and Hotter Summers Yearly?

• Sun is the source of heat and light on Earth.
• But the gradual increase in temperature during summer is because of the rise in carbon dioxide levels in nature.
• Carbon dioxide can absorb heat; hence, an increase in its level leads to higher temperatures.
