27. Template by Bill Arcuri, WCSD Continents change position over time 200 Wegener’s hypothesis of Continental Drift states this.

28. Template by Bill Arcuri, WCSD What is Earth’s continents were once in a single landmass and gradually moved apart

29. Template by Bill Arcuri, WCSD Continents change position over time 300 Wegener used these three facts to support his theory of continental drift. Daily Double!!!

30. Template by Bill Arcuri, WCSD What is (1)Mesosaurus fossils found only in Brazil and West Africa, (2) rock formations in Brazil match those in western Africa; limestone formations in the Appalachian mountains match those the Highlands of Scotland, and (3) fossils of tropical plants are found in Greenland; rocks in South Africa were scratched by sheets of ice?

31. Template by Bill Arcuri, WCSD Continents change position over time 400 The discovery of these helped scientists prove Wegener’s hypothesis of Continental drift correct.

32. Template by Bill Arcuri, WCSD What are mid-ocean ridges and deep sea trenches?

33. Template by Bill Arcuri, WCSD Continents change position over time 500 Scientists combined Wegener’s hypothesis of Continental Drift and mapping of the sea floor to develop this.

34. Template by Bill Arcuri, WCSD What is the theory of Plate Tectonics?

35. Template by Bill Arcuri, WCSD Plates move apart 100 The name of the boundary where plates move apart.

36. Template by Bill Arcuri, WCSD What is a divergent boundary.

37. Template by Bill Arcuri, WCSD Plates move apart 200 At a mid-ocean ridge, the pattern formed by magnetic minerals A) is randomly arranged at the ridge B) shows that hot spots in Earth's mantle cause volcanoes to form C) is the same on either side of the ridge D) is older along mid-ocean ridges and younger near ocean trenches

38. Template by Bill Arcuri, WCSD What is C) is the same on either side of the ridge?

39. Template by Bill Arcuri, WCSD Plates move apart 300 This is why scientists believe that the Earth’s magnetic poles have changed several times over the history of the Earth.

40. Template by Bill Arcuri, WCSD What is the rock on both sides of a mid-ocean ridge or rift valley aligns with the poles then switches direction of polarity several times as you move further away from the ridge?

41. Template by Bill Arcuri, WCSD Plates move apart 400 This is how hot spots can be used to track plate movement.

42. Template by Bill Arcuri, WCSD What is the hot spot stays in the same spot while the plate moves which creates a chain of volcanic islands?

43. Template by Bill Arcuri, WCSD Plates move apart 500 The names of three different types of boundaries and what they do.

44. Template by Bill Arcuri, WCSD What is 1) Divergent boundary where plates move apart 2) convergent boundary where plates come together 3) Transform boundary where plates scrape past each other?

45. Template by Bill Arcuri, WCSD Plates converge and scrape past each other 100 This is called Continental- Continental collision and an example of what it forms.

46. Template by Bill Arcuri, WCSD What is two continental plates colliding, crumpling and folding the rock in between. The Alps and Himalayas are examples of this.

47. Template by Bill Arcuri, WCSD Plates converge and scrape past each other 200 The type of plates that are colliding at D in the diagram below.

48. Template by Bill Arcuri, WCSD What is oceanic crust with oceanic crust?

49. Template by Bill Arcuri, WCSD Plates converge and scrape past each other 300 This is the name of the boundary at A and what happens at that boundary

50. Template by Bill Arcuri, WCSD What is transform boundary where plates slide past each other and crust is neither created nor destroyed?

51. Template by Bill Arcuri, WCSD Plates converge and scrape past each other 400 This happens when an oceanic plate and a continental plate collide. (name the collision and give an example of what forms there)

52. Template by Bill Arcuri, WCSD What is oceanic-continental collision? It forms deep ocean trenches and costal mountains.

53. Template by Bill Arcuri, WCSD Plates converge and scrape past each other 500 In oceanic-oceanic subduction, one plate sinks under another. Which one sinks? Why? And what does it form?

54. Template by Bill Arcuri, WCSD The older oceanic plate sinks because it is denser and it forms island arcs and deep ocean trenches.

55. Template by Bill Arcuri, WCSD Metric system 100 Kg in 1000 grams.

56. Template by Bill Arcuri, WCSD What is 1 Kilogram?

57. Template by Bill Arcuri, WCSD Metric system 200 Formula of density (use m=mass, d=density and v=volume)

58. Template by Bill Arcuri, WCSD What is density=mass/volume or d=m/v?

59. Template by Bill Arcuri, WCSD Metric system 300 Another name for.001 second.

60. Template by Bill Arcuri, WCSD What is a millisecond?

61. Template by Bill Arcuri, WCSD Metric system 400 Kilometers in five thousand meters.

62. Template by Bill Arcuri, WCSD What are five kilometers?

63. Template by Bill Arcuri, WCSD Metric system 500 The name for one billionth of a meter

64. Template by Bill Arcuri, WCSD What is a nanometer?

65. Template by Bill Arcuri, WCSD Final Jeopardy The feature labeled E is a volcanic island. Describe how it formed.

66. Template by Bill Arcuri, WCSD Click Once to Begin What is A volcanic island may form when two oceanic plates collide. One of these plates sinks into the asthenosphere. As the plate sinks, parts of it melt to form magma. This magma fuels an underwater volcano. The volcano eventually rises above sea level and becomes an island.
