Why can air in warm humid regions contain more water vapour?
Answer and explanation
Correct answer: Higher evaporation and greater holding capacity of warm air
The governing concept is evaporation and the temperature dependence of air’s moisture-holding capacity. Warm surfaces provide more energy for liquid water to evaporate, and warmer air can contain more water vapour before reaching saturation than colder air. If moisture is available, both effects support higher humidity. Thus A is correct. Argon abundance, ozone absence and nitrogen shortage do not explain the basic reason, so B, C and D are distractors.
