Question

How does altitude affect atmospheric temperature

Answer 1

Answer:

As the altitude increases, the air temperature decreases. As the altitude increases the number of air molecules decreases, thus the average of their kinetic energy decreases.

Answer 2

As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands), and the temperature decreases.
