The importance of pollutant gases like SO₂ in the atmosphere is most closely linked with which problem?
Answer and explanation
Correct answer: Acid rain
The governing concept is atmospheric pollution and acid deposition. Sulphur dioxide can be oxidised in the atmosphere and, after dissolving or reacting in cloud droplets, contribute to sulphuric acids. These acidic substances may return to the surface through rain or other precipitation, producing acid rain. Option C is therefore correct. Tides, eclipses, and mountain building are controlled by unrelated astronomical or geological processes.
