In which layer does temperature become minimum before a sharp rise starts in the thermosphere above?
Answer and explanation
Correct answer: Mesosphere
The governing concept is the temperature pattern across atmospheric layers. Temperature generally falls through the mesosphere and reaches its minimum near the mesopause, the boundary at its top. Above this boundary, absorption of energetic solar radiation causes temperature to rise through the thermosphere. Therefore option A, the mesosphere, is correct. The stratosphere warms upward, the troposphere is the lowest weather layer, and the exosphere lies far above the thermosphere, so the other choices do not fit.
