Why does temperature generally decrease with height in the mesosphere?
Answer and explanation
Correct answer: Because gases absorbing solar radiation are very few there
The governing concept is the vertical temperature structure of the atmosphere. In the mesosphere, there is relatively little absorption of solar energy compared with the stratosphere, and the air is extremely thin. As altitude increases, less heat is retained, so temperature falls and becomes very low near the mesopause. Thus option A is correct. Water vapour is not greatest there, pressure is far below sea-level pressure, and maximum ozone heating is associated with the stratosphere.
