What happens to air pressure as altitude increases

A. Air temperature increases

B. Air temperature decreases

C. Air temperature does not change

D. Air temperature depends on the amount of organisms in the area

Pressure with Height: 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 ...
