Answer 2

1. Excessive use of fossil fuels i.e., coal and petroleum. Because burning of these fossil fuels
adds carbon particles to the atmosphere which causes smog. It produces huge amount of
carbon monoxide and carbon dioxide as well.

2. Use of chiorofluorocarbons (CFCs) in refrigeration is responsible for depletion of ozone
layer. Venus is closer to the Sun and Mars is further away, and earth is not much closer or nor far from sun.
