In the earth's atmosphere, the atmospheric pressure ________
A
Increases with height
B
Decreases with height
C
Remains constant with height
D
First increases and then decreases with height
Correct Answer: Decreases with height
In the earth's atmosphere, the atmospheric pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.
