Near the upper boundary of which layer does temperature reach a minimum before beginning to increase in the thermosphere above?
Answer and explanation
Correct answer: Mesosphere
The governing concept is the sequence of atmospheric temperature changes with altitude. Temperature falls through the mesosphere and reaches its lowest upper-boundary value at the mesopause, the boundary between the mesosphere and thermosphere. Above the mesopause, absorption of high-energy solar radiation causes temperature to increase in the thermosphere. The other options identify different layers and boundaries, so option C is correct.
