What atmospheric reason can explain relatively higher night temperature in humid regions?
Answer and explanation
Correct answer: Water vapour can absorb longwave heat
The governing concept is the greenhouse effect of water vapour. During the night, Earth’s surface emits longwave radiation. Water vapour absorbs part of this outgoing energy and re-emits it in different directions, including downward, which reduces the rate of surface cooling. Thus option A is correct. Nitrogen does not create the Sun, dust cannot remove gravity, and ozone is not the stated cause of generally warmer humid nights.
