2. This is how fast the plates move every year.

3. What is 1-12 cm?

4. These are the two main types of evidence that support the hypothesis of continental drift.

5. What are the presence of the same fossils and rocks on different continents?

6. This is when two plates move together and the force that causes it.

7. What is a convergent plate boundary and compression?

8. This is when two plates move away from each other and the force that causes it.

9. What are a divergent plate boundary and tension?

10. This is when two plates slide past each other and the force that causes it.

11. What is a transform boundary and shear?

12. This is the area where one plate slides under another.

13. What is the subduction zone?

14. Convection in the mantle causes this.

15. What are the tectonic plates to move?

16. These are the two types of evidence that scientists have used to support the theory of plate tectonics.

17. What are fossil evidence and geological evidence?

18. This is the hypothesis that the continents have slowly moved to their current locations.

19. What is continental drift?

20. This is the name of the scientist who first proposed the hypothesis of plate tectonics.

21. Who is Alfred Wegener?

22. These are formed when layers of lava and volcanic ash erupt and build up.

23. What are volcanoes?

24. This is formed when the top of a volcano collapses down.

25. What is a caldera?

26. These are long streams of molten rock.

27. What are lava flows?

28. This type of volcano has a gentle slope and is formed from lava flows.

29. What is a shield volcano?

30. These are locations where volcanoes form far from plate boundaries.

31. What are hot spots?

32. This is the process of changing the composition of the rocks and minerals.

33. What is chemical weathering?

34. This is the process of breaking rock into small pieces without changing the composition of the rock

35. What is physical weathering?

36. This is what happens to sediment eroded by water, ice, and wind when it slows down or stops moving.

37. What is the sediment is deposited in a new location?

38. Sand dunes are and example of erosion and deposition by ___________.

39. What is wind?

40. Frost wedging is an example of this type of weathering.

41. What is physical weathering?

42. This is how long it takes for soil to form.

43. What is hundreds to thousands of years?

44. This is the type of climate that soil forms the fastest in.

45. What are hot and wet climates?

46. These are the components make up soil.

47. What are weathered rock, mineral material, organic matter, water, and air.

48. This is erosion.

49. What is the process that moves materials from place to place?

50. A rock slowly dissolving in water and breaking into different separate elements is an example of this type of weathering.

51. What is chemical weathering?
