Presentation Transcript

  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 Northern Lights - Auroras Meteor

  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 Jet plane Ozone layer

  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

  10. Picture of Layers
