  1. 1. PLEASE HELP US ALIENS!!! SAVE PLANET EARTH!!!
  2. 2. The Earth’s Interior Structure
  3. 3. Crust Mantle Outer Core Inner Core
  4. 4. Here is a better look of the Earth’s structure with its Lithosphere and Asthenosphere
  5. 5. What is the Lithosphere and Asthenosphere <ul><li>Lithosphere- the thin outer shell of the Earth consisting of the Crust and the upper Mantle </li></ul><ul><li>Asthenosphere- the zone of the Mantle beneath the Lithosphere that consists of slowly flowing solid rock. </li></ul>
  6. 6. The Problem in the Interior!!!
  7. 7. Crust Mantle Outer Core Inner Core As you can see the Earth’s core has shifted 200 miles towards India.
  8. 8. Other Things Wrong With the Earth Earthquakes Volcanoes Tsunamis
  9. 9. Plate Tectonics
  10. 10. What is Plate Tectonics? <ul><li>The theory that the Earth’s surface is made up of large moving plates. </li></ul>
  11. 11. Pangea the “all land” 200000000 years ago
  12. 12. The earth 100000000 years ago
  13. 13. The earth 20 million years ago
  14. 14. The earth today
  15. 15. The earth 50 million years in the future
  16. 16. Plate Boundaries
  17. 18. Plate Boundaries
  18. 19. Two plates move apart from each other Plate Boundaries Two plates moving towards into each other and build up. Two plates slide against each other.
  19. 23. <ul><li>Below is a graph of the rock ages for the map on top. </li></ul>                                                                                                                Below is a graph of the rock ages for the map on top.                                                                                      
  20. 26. Mid ocean ridge
  21. 29. Faults
  22. 30. Faults
  23. 31. What is a Fault? A crack in Earth created when rocks on either of a break move.
  24. 34. Earthquakes
  25. 36. <ul><li>Epicenter- the point on Earth’s surface directly above the focus of an earthquake </li></ul><ul><li>Focus- the area along a fault at which a slippage first occurs initiating an earthquake </li></ul>
  26. 37. P waves- fastest waves, they are called push and pull waves, they travel through liquids and solids
  27. 38. S waves- wave that a slower than primary waves , they are called side to side waves, and they move like a snake, they only travel through a solid
  28. 39. Surface waves- slowest waves, called up and down waves, and they only travel on the surface
  29. 42. Seismograph
  30. 44. Volcanos
  31. 45. Spreading center
  32. 46. There are three different types of Volcanoes
  33. 47. Cinder Cone Volcano
  34. 48. Compositive Volcano Competitive Volcanoes are built out of layers of cinders, ash and lava
  35. 49. Shield volcano Volcanoes built out of lava are called sloping mountain or Shield Volcano
  36. 54. Island arc
  37. 55. Tsunami
  38. 59. Thank you for saving the earth !!!
