Convection:
A)is less important to making up the atmosphere's radiative energy deficit than is conduction.
B)typically transfers heat downward during the day.
C)plays no significant role at night.
D)helps circulate heat throughout the atmosphere.

Question

Quizplus · Accepted Answer

Convection helps circulate heat throughout the atmosphere, which is an important process in redistributing heat from the equator to the poles and vice versa. Conduction plays a relatively small role in the overall heat transfer in the atmosphere, and convection can occur both upward and downward depending on temperature gradients. It also occurs both during the day and at night.
