Lapse rate is the change of temperature over altitude.

Explanation:

As a parcel of air rises it cools, as it lowers it warms. It does this adiabatically, meaning without mixing with the surrounding air. The reason the temperature changes is because the pressure changes.
Best example I can think of is when the wind blows up a mountain slope.
