Why is methane considered important in the atmosphere?
Answer and explanation
Correct answer: It is a trace greenhouse gas
Methane is present in the atmosphere in a much smaller concentration than nitrogen or oxygen, but it absorbs outgoing infrared radiation and contributes to the greenhouse effect. Its climatic influence is therefore greater than its small concentration might suggest. Option C is correct. Oxygen supports respiration, nitrogen is the most abundant gas, and a condensation nucleus is usually a particle rather than methane itself.
