What is the primary cause of wind? a The even heating of earth
b Air Pressure differences
c The rotation of earth
d Similar air pressure

B

Explanation:

The wind is caused by differences in atmospheric pressure. When a difference in atmospheric pressure exists, air moves from the higher to the lower pressure area, resulting in winds of various speeds. On a rotating planet, air will also be deflected by the Coriolis effect, except exactly on the equator.

i'd say that the moon rock is about 2.2 billion years old.
