Structure of the Atmosphere

Troposphere Layer closest to Earth Contains most mass Weather and pollution occur here Decrease in temp with altitude Varies in height Tropopause is the most upper part

Stratosphere Above tropopause Made primarily of ozone Gradual increase in temp until you get to the upper most part called the stratopause

Mesosphere No ozone here, so the temp decreases with height Above this is the mesopause

Thermosphere Contains very little mass Layer increases with temp with height Contains the ionosphere

Exosphere Outermost layer of the atmosphere Mainly composed of H and He Above this layer is outer space
