2. What was the name of the super continent?

3. Pangaea

4. Who came up with the theory of continental drift?

5. Alfred Wegener

6. Describe the theory of continental drift in detail

7. continents move away from each other Started as one large continent 250 million years ago Plates move 1-2 cm per year

8. Give 3 pieces of evidence for continental drift

9. Fossils found where they couldn’t live Continents seem to fit together Mineral deposits on edges of continents

10. Name the plate that we currently live on and the plate directly to the West of us

11. North American plate & Pacific plate

12. Name the boundary that rubs past in opposite directions and tell what it can cause

13. Transform Earthquakes

14. Name the boundary where plates come toward each other and tell what it can cause

15. Convergent Mountains

16. Name the boundary where plates go away from each other and tell what it can cause

17. Divergent Trenches and volcanoes

18. Name the boundary where one plate sinks under another and tell what it can cause

19. Subduction Volcanoes

20. Name the volcano that is an exception to the rule and explain how it was made

21. Hawaii Magma pushing through the middle of a plate

22. Name all three seismic waves

23. P-Primary S-Secondary L-Surface

24. What can Primary & Secondary waves travel through

25. P-solid and liquid S-solid only

26. Name the transform boundary in the U.S.

27. San Andreas Fault

28. How do geologist know that the outer core is liquid?

29. How do geologist know that the core is liquid? Because the S waves do not come out the opposite side of the earth (S wave shadow)

30. How do geologist know that the inner core is solid?

31. Because of the way that the P waves bend due to refraction as they go through the Earth

42. What is the difference between Magma & lava?

43. Magma is in the Earth, Lava is on the Earth

44. What are the scientists called who study the Earth?

45. Geologists

46. How long ago did Pangaea exist?

47. 200-300 million years ago

48. What allows the plates to move?

49. The asthenosphere
