GEOLOGY

Detailed explanation-1: -Temperature increases as you gain altitude in the stratosphere and the thermosphere. Temperature decreases as you gain altitude in the troposphere and mesosphere.

Detailed explanation-2: -The basic answer is that the farther away you get from the earth, the thinner the atmosphere gets. The total heat content of a system is directly related to the amount of matter present, so it is cooler at higher elevations.

Detailed explanation-3: -While still extremely thin, the gases of the thermosphere become increasingly denser as one descends toward the earth. As such, incoming high energy ultraviolet and x-ray radiation from the sun begins to be absorbed by the molecules in this layer and causes a large temperature increase.

Detailed explanation-4: -Temperature decreases with altitude because the troposphere is warmed from below, through absorption and re-emission of incoming solar radiation by the Earth’s surface, rather than being warmed from above by incoming solar radiation.

Detailed explanation-5: -Pressure with Height: pressure decreases with increasing altitude.
