Why can trace gases be effective despite small amounts?
Answer and explanation
Correct answer: Some gases play special roles in radiation or chemical processes.
The governing concept is that atmospheric importance depends on function, not only concentration. Trace gases such as carbon dioxide and ozone can absorb or emit particular wavelengths of radiation, while ozone also participates in protective chemical processes. Therefore, even a small quantity can influence temperature, climate, or ultraviolet protection. Option A is correct; B falsely claims they exceed nitrogen, and C and D contradict their nature.
