Question

Acid rain is due to the precipitation of ______.

विकल्प

• CO₂

• hydrogen sulphide

• oxides of sulphur

Answer 1

Acid rain is due to the precipitation of oxides of sulphur.

Explanation:

Oxides of sulphur react with atmospheric water to form acids that return to Earth in precipitation. Carbon dioxide makes ordinary rain slightly acidic, while CFCs are chiefly associated with ozone depletion.
