Why is the dominance of N2 in the atmosphere considered a cause of systemic stability rather than only a fact of quantity?
Answer and explanation
Correct answer: Because it is relatively less reactive and moderates the combustion potential of O2
The governing concept is atmospheric chemical stability. Nitrogen is abundant but comparatively unreactive under ordinary atmospheric conditions, so it dilutes oxygen and reduces the likelihood of uncontrolled, widespread combustion and rapid oxidation. Its large quantity therefore has a stabilising chemical effect, not merely a numerical significance. Option A is correct. Clouds, ultraviolet absorption and tides are governed mainly by other processes and substances, so B, C and D are unsuitable.
