6th Grade Ch 1 Sec 3 Layers Of The Atmosphere

  1. 1. Ch. 1 Sec. 3 Layers of the Atmosphere
  2. 2. Layers of the atmosphere are classified by changes in temp.
  3. 4. troposphere <ul><li>lowest layer </li></ul><ul><li>from 0  12 km </li></ul><ul><li>we live in it </li></ul>
  4. 5. Weather occurs in the troposphere.
  5. 7. stratosphere <ul><li>12  50 km </li></ul><ul><li>absorbs UV radiation </li></ul><ul><li>ozone layer </li></ul><ul><li>weather balloons </li></ul>
  6. 9. mesosphere <ul><li>50  80 km </li></ul><ul><li>meteors burn up </li></ul><ul><li>coldest part of atmosphere </li></ul>
  7. 10. Most me teoroids burn up in the me sosphere.
  8. 12. thermosphere <ul><li>outermost layer </li></ul><ul><li>80 km  to outer space </li></ul><ul><li>no definite outer limit </li></ul><ul><li>divided into 2 layers: </li></ul>
  9. 13. <ul><li>ionosphere </li></ul><ul><li>lower layer </li></ul><ul><li>aurora borealis </li></ul>
  10. 14. AURORA BOREALIS
  11. 18. Communication satellites orbit Earth in the exosphere.
  12. 19. 2. exosphere = outer layer satellite
  13. 20. Name that layer
  14. 21. AURORA BOREALIS thermosphere (ionosphere)
  15. 22. stratosphere <ul><li>absorbs UV radiation </li></ul>
  16. 23. troposphere <ul><li>lowest layer </li></ul><ul><li>we live in it </li></ul>
  17. 24. mesosphere <ul><li>meteors burn up </li></ul>
  18. 25. stratosphere <ul><li>ozone layer </li></ul>
  19. 26. mesosphere <ul><li>coldest part of atmosphere </li></ul>
  20. 27. thermosphere (exosphere) = outer layer satellite
  21. 28. Weather occurs in the troposphere.
  22. 29. Communication satellites orbit Earth in the exosphere (thermosphere).
