Question

air at the equator is ______? a.rising b.sinking c.staying at the same level d. moving north e. stagnant

Answer 1

Think of the old saying "warm air rises". Air near the equator is going to rise towards the poles of the planet, cool, and then return towards the equator.

Answer 2

Air at the equator is warm.
Warm air rises. [Not the rising to the poles, but rising on the land]


As the warm air rises, a low pressure system gets created from where the air rose. This low pressure attracts more wind, cooler air from the poles to replace it.

So I think it should be Option 'A'. :)
