1. Plate Tectonics Jeopardy Game

2. Game On! Final Challenge

3. Ie know my boundaries for 10 • This type of plate boundary occurs when two plates slide past each other forming a zigzag plate margin. The San Andreas Fault in California is an example of a ______ boundary.

4. I know my boundaries for 100 • What are Transform Boundaries?

5. I know my boundaries for 200 • These are boundaries where plates move together and form a collision or subduction zone.

6. I know my boundaries for 200 • What are • Convergent Boundaries

7. I know my boundaries 300 • These boundaries are created when plates move apart and new material is added to the Earth’s crust. An example is the Mid-Atlantic Ridge.

8. I know my boundaries 300 What Are Divergent Boundaries • What are • divergent boundaries?

9. I know my boundaries 400 • Steep sided depressions that form at divergent boundaries are called ________. • There is one in East Africa

10. I know my boundaries 400 Rift Valleys • What are • Rift Valleys

11. I know my boundaries 500 • This forms a trench, a subduction zone, and possibly an island arc. Be specific!

12. I know my boundaries 500 • What are oceanic-oceanic convergent boundaries.

13. Boundaries-2 for 100 • When an oceanic plate collides with a continental plate deep trenches may form. The most famous of these is an 11,000 meter deep trench called the _________.

14. Boundaries-2 for 100 • What is • The Marianas Trench?

15. Boundaries-2 for 200 • When plates collide, one plate may slide beneath another creating an area called a __________ zone.

16. Boundaries-2 for 200 • What is a • Subduction Zone?

17. Boundaries-2 for 300 • When the European Plate and the Indian Plate collided the two continents formed a large mountain range called ________.

18. Boundaries-2 for 300 • What are the • Himalayas?

19. Boundaries-2 for 400 • Volcanic arcs and oceanic trenches encircle the Pacific Basin creating a zone of frequent earthquakes and volcanic eruptions. This large area of convergence and subduction is called _________ ________ ___ __________.

20. Boundaries-2 for 400 • What is • The Ring of Fire?

21. Boundaries-2 for 500 • The vast majority of earthquakes and volcanoes occur along ___________.

22. Boundaries-2 for 500 • What are • Plate Boundaries? • Or • What is • The Pacific Rim?

23. History of Tectonics for 100 • The theory that the continents are constantly moving over the surface of the earth is called:

24. History of Tectonics for 100 • What is • The Theory of Continental Drift?

25. History of Tectonics for 200 • The scientist who proposed that the continents were once part of a super continent.

26. History of Tectonics for 200 • Who is • Alfred Wegner?

27. History of Tectonics for 300 • The name of the super continent theorized by Alfred Wegner.

28. History of Tectonics for 300 • What is Pangaea?

29. History of Tectonics for 400 • When Paleontologists found evidence of similar __________ on continents separated by great geographic distance, the idea of a super continent Pangaea was supported.

30. History of Tectonics for 400 • What are species or fossils?

31. History of Tectonics for 500 • Scientists studying _______________, the detection of the Earth’s movement, proved that earthquakes and volcanoes seem to align along belts that define the tectonic plates.

32. History of Tectonics for 500 • What is Seismology?

33. The Earth's Layers for 100 • The continents and the oceans are part of this layer of the earth’s surface. It is the lightest layer of the Earth.

34. The Earth's Layers for 100 • What is the Crust?

35. The Earth's Layers for 200 • A semi-liquid layer of the Mantle just under the lithosphere that flows as a result of convection currents and causes plates to move.

36. The Earth's Layers for 200 • What is the aesthenosphere?

37. The Earth's Layers for 300 • Fluid movements just below the lithosphere that causes earthquakes, mountain building and volcanoes.

38. The Earth's Layers for 300 • What are convection currents?

39. The Earth's Layers for 400 • This layer is composed of solid iron and nickel. Although it is the smallest layer, it is the heaviest.

40. The Earth's Layers for 400 • What is the inner core?

41. The Earth's Layers for 500 • This layer is liquid iron and nickel.

42. The Earth's Layers for 500 • What is the outer core?

43. Fact Maniac for 100 • Most of these are due to the release of built-up energy along plate boundaries. When the pressure on a fault overcomes the friction on a fault, this occurs.

44. What is an earthquake?

45. Fact Maniac for 200 • Earthquakes release energy in the form of these types of waves

46. Fact Maniac for 200 • What are • primary and secondary waves?

47. Fact Maniac for 300 • The amount of energy released during an Earthquake is measured by seismographs and reported as _____________.

48. Fact Maniac for 300 • What is magnitude?

49. Fact Maniac for 400 • Inside the earth’s core, a reaction occurs which that breaks heavy element into smaller pieces causing a chain reaction. This event is called

50. Fact Maniac for 400 • What is Fission?
