1. Layers of the Atmosphere Name Class Period

2. Thermosphere Upper level of the atmosphere Extremely high temperature Doesn’t feel hot because of so few air molecules Auroras occur here (Northern Lights) Some sattellites orbit here

3. Thermosphere

4. Mesosphere Air is thin Friction between meteors and air molecules burn up most meteors Trail of burning meteors is a shooting star

5. Mesosphere Meteor Northern Lights - Auroras

6. Stratosphere Temperature increase from bottom to top Higher temperature because of ozone layer absorbs from ultraviolet rays Some jet planes fly here to avoid storms

7. Stratosphere Ozone layer Jet plane

8. Troposphere Layer where nearly all life exists Tropo means turning, layer where air turns Layer where Earth’s weather occurs ¾ of atmosphere by weight Holds nearly all water vapor Approximately 5 miles high ( 11 miles at equator

9. Troposphere Airplanes Life Weather
