2. This makes up most of the Earth’s mass.

3. What is the mantle.

4. The outermost layer of the Earth is called this.

5. What is lithosphere.

6. Tectonic plates consist of these types of crusts.

7. What is continental and oceanic.

8. Tectonic plates float on top of this layer.

9. What is asthenosphere.

10. These are the 5 main physical layers in order from the surface to the center of the Earth.

11. What is the lithosphere, asthenosphere, mesosphere, outer core and inner core.

12. Wegener thought all continents were once together in one large continent called this.

13. What is Pangaea.

14. Sea floor spreading takes place at these areas.

15. What are mid ocean ridges

16. The fact that similar fossils are found on both sides of the ocean is evidence of this.

17. What is Continental Drift.

18. The theory of Continental Drift explains this about our continents.

19. Why our continents move.

20. New oceanic lithosphere forms as a result of this.

21. What is sea floor spreading.

22. This type of boundary occurs where 2 plates collide.

23. What is a convergent boundary.

24. This type of fault is caused by compression.

25. What is a reverse fault.

26. This is an area where 2 tectonic plates meet.

27. What are boundaries.

28. Plates slide past each other at this type of boundary.

29. What is a transform boundary.

30. This type of fault occurs because of tension.

31. What are normal faults.

32. This is the amount of force per area on a given material.

33. What is stress.

34. Stress squeezing an object is this.

35. What is compression.

36. Pulling an object is this.

37. What is tension.

38. This is when Earth’s magnetic poles change place.

39. What is magnetic reversal.

40. This is the strong lower part of the mantle that lies beneath the asthenosphere.

41. What is the mesosphere.

42. This is the solid dense center of our planet.

43. What is the inner core.

44. This type of boundary forms when 2 plates separate.

45. What is a divergent boundary.

46. Earthquakes produce these.

47. What are seismic waves.

48. This is the liquid layer of the Earth.

49. What is the outer core.

50. Scientists use the Global Positioning System (GPS) for this.

51. What is to measure tectonic plate movement.
