15. evidence for age of earth

16. Fossils

17. are

18. Harry Hess

19. Considered one of the founding fathers of the theory of plate tectonics

20. Age of earth

21. Geological time scale shows us how old the earth is

22. Forces of nature

23. Seismic Waves

24. Sonar

25. Theory

26. Evidence

27. IS everything we have done. Everything on her is evidence of how old the earth is. This can all help us

28. Theory

29. Physical Chemical

30. Harry hess came along and discovered that the bottom of the sea-floor had ridges in the center and trenches near continents using sonar.                                    Evidence: Magentic Strips, age of rocks are younger in the center and increase in age as you get closer to trenches, molten material erupting from the center of the mid-ocean ridge.

31. The study of plate movement on earth driven by convection currents in teh mantle          Three types of movement     Spreading(causes ridgesto form and volcanic eruptions                                    Colliding(Volcanoes and mountains to form                                                              Sliding(causes faults and folds

32. Eight forces of nature that shape our land over varying times(slow and fast) and spatial scales(small changes to huge changes                                                Plate movement, Folds and Faults, Earthquakes, Volcanic eruptions, Weathering, Glacier erosion, wind erosion, and water erosion

33. Wind Erosion

34. Glacier Erosion

35. Water Erosion

36. Volcanic eruptions

37. Weathering

38. Layers

39. Crust

40. Mantle

41. Lithosphere

42. Asthensophere

43. Outer Core

44. Inner Core

45. Internal

46. Creates and destroys the sea floor.

47. Creates hurricanes, sand dunes and tornadoes. They also move around dirt.

48. Oceanic Crust

49. Sea Floor Spreading

50. Deep ocean trench

51. Mid Ocean Ridge

52. Continental Drift

53. Mid-ocean ridge

54. Are created by

55. Convection Currents

56. Considered one that theorize the movement of continental plates

57. Inside earth

58. hurricanes

59. Subduction


61. Valleys

62. Creates

63. Smooths things out

64. Alfred Wegenger

65. Oceanic Crust

66. Continental Crust

67. The Convection currents in the Mantle move the Earth's lithosphere(which contains our plates)

68. Alfred Wegener discovered rock patterens, fossils, and glacier evidence, and the Jigsaw fit of continents to support the idea that our continents were once together. Scientific communtiy did not believe him and thought he was crazy because he could not explain HOW they move.

69. Geological time scale                                Evidence   Rock and fossil data. A time scale is spread out where it has only been in the past 500 million years that all life we know has evidence.
