Why is the mesopause counted among the coldest regions of the atmosphere?
Answer and explanation
Correct answer: Because it is linked with minimum temperature at the upper mesosphere
The governing concept is the temperature pattern through atmospheric layers. In the mesosphere, temperature generally falls with height and reaches an extremely low value near its upper boundary, the mesopause. Hence option A is correct. The mesopause is not the lower boundary of the stratosphere; that boundary is the tropopause. It is also far above the moist surface atmosphere, so options C and D are incorrect.
