Why is the study of trace gases in the atmosphere necessary?
Answer and explanation
Correct answer: Because even in small quantities they affect radiation, chemistry and pollution
The governing concept is that atmospheric importance depends on chemical and radiative activity, not merely concentration. Trace gases such as ozone, methane and nitrous oxide can absorb radiation, participate in chemical reactions and influence air quality or climate even when present in small amounts. Hence option D is correct. The other choices wrongly assume that low abundance means no effect or that gases alter Earth’s shape.
