As you go higher, there are less air molecules (less weight) on a given area this is basically one reason why it decreases. From the barometric formula, one can get the relation between the pressure and altitude. It's defined as. P = P 0 e − m g h k T. so the relation between pressure and altitude is P ∝ e − h.

The density of air decreases with height. There are two reasons: at higher altitudes, there is less air pushing down from above, and gravity is weaker farther from Earth's center. So at higher altitudes, air molecules can spread out more, and air density decreases ( Figure below). rv connection in lawton

Nettet10. okt. 2024 · 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. If the humidity is at 100 percent (because it’s snowing), the temperature decreases more slowly with height.”
