Which option correctly relates atmospheric gas percentages?
Answer and explanation
Correct answer: Nitrogen is more abundant than oxygen
In dry air near Earth’s surface, nitrogen makes up approximately 78% and oxygen approximately 21% by volume. Thus nitrogen is clearly more abundant than oxygen, making option A correct. Argon is present at roughly 0.93%, and carbon dioxide is only a small fraction, so neither can exceed nitrogen or oxygen in the comparisons given. Water vapour varies by place and time.
