The Earth-atmosphere radiation system is best described by which of the following?
A)if the surface and the atmosphere are considered separately,neither exhibits a balanced radiation budget.
B)the surface exhibits an overall negative radiation balance.
C)the atmosphere exhibits an overall positive radiation balance.
D)only convection transfers heat energy to the atmosphere from the surface.
E)latent heat is not important in this system.

Question

Quizplus · Accepted Answer

The Earth-atmosphere radiation system is not in balance if the surface and the atmosphere are considered separately. The surface receives more incoming radiation than it emits, while the atmosphere emits more radiation to space than it receives from the surface. Thus, the system as a whole is in balance, but not the individual components. Option B and C are incorrect as they show a negative and positive radiation balance respectively, which is not applicable to the system as a whole. Option D is incorrect as radiation is the primary mode of heat transfer in the atmosphere. Option E is incorrect as latent heat plays a significant role in the Earth-atmosphere radiation system.
