As air rises, the pressure decreases. It is this lower pressure at higher altitudes that causes the temperature to be colder on top of a mountain than at sea level.
Why is it colder at the top of a mountain?
But why should the top of a mountain be colder than the bottom? At the top of a mountain, air cools because as air rises it cools. … If the air pressure is 1000 millibar, that is because there is approximately 10 tonnes of air above every square metre of ground. This air pressure is literally pressing down on everything.
