Question

1. the polar cells are the convection cells nearest the poles. (10 points)

a. what are the temperature and pressure conditions of the surface air at the poles? (4 points)
b. what are the pressure conditions of the air above the poles? (2 points)
c. how does air move at the poles? (4 points)
a. |

Explanation:

A. The surface air at the Poles is very cold and has high - pressure. Cold air is dense and sinks, creating high - pressure zones.
B. The air above the Poles is also high - pressure as the cold, dense air sinks.
C. At the Poles, cold, dense air sinks at the surface and then moves outwards towards lower latitudes as part of the polar easterlies.

Answer:

A. Cold temperature and high - pressure.
B. High - pressure.
C. Cold air sinks at the surface and moves outwards towards lower latitudes.
