If a thermal profile shows temperature decreasing upward in the lowest layer, which layer is it?
Answer and explanation
Correct answer: Troposphere
The governing concept is the environmental lapse rate: in the troposphere, temperature generally falls as altitude increases because the surface is heated mainly from below and then warms the air above it. This upward decrease distinguishes it from the stratosphere, where ozone absorption produces warming with height, and from the upper layers, which have different thermal patterns. Therefore, option C is correct.
