The air at high altitudes is colder that that at lower altitudes, but it is less dense because it is under lower pressure. If you were to force high altitude air down to ground level it would compress and heat up, in most cases becoming warmer than the surrounding air. In such a situation the atmosphere is said to be unstable. In some cases, however, a sinking mass of air might not become warmer than the surroundings. In such cases warm air rises and cool air sinks in a process called convection.
