Why is methane important among atmospheric elements?
Answer and explanation
Correct answer: Because it can be a powerful greenhouse gas in small amounts
The governing concept is the climatic importance of trace greenhouse gases. Methane is present in a much smaller concentration than nitrogen or oxygen, but each molecule can absorb infrared radiation effectively. Changes in methane concentration can therefore contribute to warming, even though methane is not the main gas of air. Option A is correct; the other choices confuse abundance, cloud formation and ultraviolet radiation.
