In which layer is the main heating source upper solar radiation rather than the surface?
Answer and explanation
Correct answer: Thermosphere
The governing concept is the direction and source of atmospheric heating. The thermosphere absorbs energetic solar ultraviolet and X-ray radiation directly, so its heating is linked mainly to upper solar input rather than contact with the Earth’s surface. Option A is correct. The lower troposphere, surface boundary layer, and monsoon troposphere are heated chiefly from below by the land or ocean surface and are associated with weather processes.
