Question

the air pressure on mt. denali in alaska is... (select all that apply; use the figure showing air pressure with height)
a is much less than the pressure at 5000 feet above sea level.
b between 500 and 400 mb.
c less dense than the air at the surface in dekalb.
d is much greater than the atmospheric pressure at sea level.

Explanation:

Air pressure decreases with increasing altitude. Mt. Denali is very high. Sea - level pressure is around 1013 mb. Pressure at 5000 feet is higher than at even higher altitudes like Mt. Denali's. Air density also decreases with altitude.

Answer:

A. is much less than the pressure at 5000 feet above sea level.
B. between 500 and 400 mb.
C. less dense than the air at the surface in Dekalb.
