Why does temperature generally decrease from bottom to top in the troposphere?
Answer and explanation
Correct answer: The surface heats lower air through longwave radiation
The governing concept is surface-based heating of the troposphere. Earth’s surface absorbs incoming solar energy and emits longwave infrared radiation, which warms the air near the ground; as altitude increases, air pressure and density decrease, and rising air expands and cools. Therefore option A is correct. Ozone, the exosphere, and mesospheric rainfall do not explain the normal tropospheric lapse rate.
