Which option gives the correct pair of a major gas and a trace gas among atmospheric elements?
Answer and explanation
Correct answer: Nitrogen and methane
Nitrogen is the most abundant gas in dry air, making up roughly 78 percent, so it is a major atmospheric gas. Methane is present in a very small concentration, so it is classified as a trace gas, even though it has an important greenhouse effect. Dust, ash, sea salt, and clouds are not a correct major-gas/trace-gas pair, while ozone itself is a trace gas but clouds are not gases.
