Why does temperature fall and become very low near the mesopause?
Answer and explanation
Correct answer: Because heat absorption is relatively low and radiative cooling is effective at this height
The governing concept is the vertical temperature structure of the atmosphere. In the mesosphere, ozone is much less abundant than in the stratosphere, so ultraviolet absorption provides little heating. At the same time, the thin air can lose energy efficiently through radiation, causing temperature to decline upward and reach a minimum near the mesopause. Rainfall, complete absence of sunlight, and direct surface heating do not occur there, so option A is correct.
