What is the correct reason for low water vapour in high cold regions?
Answer and explanation
Correct answer: Cold air has low water vapour holding capacity
The governing concept is the temperature dependence of air’s moisture-holding capacity. Cold air can contain less water vapour before reaching saturation, and high regions are often colder and farther from strong surface evaporation sources. Consequently, the actual water-vapour content may be low there. Option A is correct. Argon does not cause rain, nitrogen remains present, and ozone does not transform into water under ordinary atmospheric conditions.
