Which gas is the second most abundant gas in the atmosphere after nitrogen?
Answer and explanation
Correct answer: Oxygen
Oxygen is the second most abundant gas in dry atmospheric air, forming about 21 percent by volume, after nitrogen at about 78 percent. Argon is present at less than 1 percent, while carbon dioxide and ozone occur in much smaller trace quantities. The wording refers to the usual composition of dry air; water vapour is variable and is not the intended choice among these options.
