Why is water vapour generally lower in high cold regions?
Answer and explanation
Correct answer: Cold air holds less water vapour and distance from sources is greater
The governing concept is the temperature dependence of atmospheric moisture capacity. Colder air can contain less water vapour before reaching saturation, so cooling often causes condensation and removal as cloud or precipitation. High regions are also commonly farther from warm surface water sources and may have lower evaporation. Therefore A is correct. Nitrogen does not become zero, ozone is not always absent, and inert argon does not produce rainfall.
