1. Structure of the Atmosphere

2. 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

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

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

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

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