Answer:

A

Step-by-step explanation:

Air lower in the atmosphere is more dense than air above, so air pressure down low is greater than air pressure higher up. (Remember those acrobats; there's a lot more pressure on the one on bottom than on the one on top.) Temperature also makes changes in air pressure.
