Why Does the temperature decreases when the altitude increases?

Temperature is measure of the thermal content of the substance. For a gas it's a measure of average kinetic energy of the molecules. As we go high up, the pressure decreases and air molecules collides less frequently which indicates lower speeds, hence lower kinetic energy and thus lower temperature.
