Question

what is the relationship between temperature and altitude in the stratosphere?

A. as altitude increases, temperature decreases

B. as altitude increases, temperature increases

C. as altitude increases, temperatures remain the same

D. as altitude increases, temperatures vary

Answer 1

The higher you go, the lesser the air pressure becomes. Atmospheric air pressure is caused by the weight of the air above it. At greater heights, the amount of air above you is less, so there is less weight pressing on the air you are in. This is the reason why the atmospheric pressure is higher at the sea-levels and lower at mountains and places of high altitudes.

Answer 2

a. an ascent in altitude leads to a decrease in temperature.
one reason is that air closer to the ground is more intensely heated than air at higher altitudes.
