It cools at the dry adiabatic lapse rate (DALR, about 9.78 C/KM), until it hits its dew point and is saturated at which point it cools at the moist adiabatic lapse rate (MALR, about 4.9 C/KM).
This happens because as air rises, its pressure decreases. If the pressure decreases then there is less pushing on the air particles and they therefore have less friction. Less friction means less kinetic energy and therefore less heat.
C=Celsius
KM=Kilometer

If the air is rising, it does not have to change temperature. But, warmer air will naturally rise above cooler air. So, if it is changing temperature, it is becoming warmer compared to the air around it. This could mean either it is actually getting warmer, or that it is getting less cooler than the air around it.

I think you are looking for a simple answer and here it is. As air rises the pressure is lower and it expands. The opposite is true as air descends the pressure increases and it compresses. This is a law of physics, cools by expansion, heats by compression. So it gets colder.

cooler. just think of a 2 story house. on the top story its alwayz colder than on the first story.
