5. $200 Crust & Upper Mantle The lithosphere is made up of what two parts of the Earth?

6. $400 Iron The core is made up of mainly this element.

7. $600 Asthenosphere What does the lithosphere float on top of?

8. $800 It contains more iron and magnesium Why is the mantle more dense than the crust?

9. $1000 Lithosphere, Asthenosphere, Mesosphere, Outer Core, Inner Core Name the 5 layers of Earth from the surface to the center (based on physical structure)

10. $200 Alfred Wegener What scientist first came up with the idea of Continental Drift?

11. $400 Pangaea 250 MYA there was a super- continent on the Earth called what?

12. $600 Because there was no mechanism for movement Why was the theory rejected at first?

13. $800 Puzzle pieces, similar rocks on coast, similar fossils on coasts, changing climate What 4 pieces of evidence did Wegener have to support his theory?

14. $1000 Laurasia & Gondwana When Pangaea broke up it formed what two continents?

15. $200 Mid-ocean ridges Where does sea-floor spreading take place?

16. $400 Magnetic minerals on the ocean floor What is the evidence for sea-floor spreading?

17. $600 When the magnetic poles change places What is a magnetic reversal?

18. $800 Centimeters What units would you use to measure the rate of sea- floor spreading?

19. $1000 Molten rock contains metal minerals that will align with the Earth’s magnetic field, then cool and stay as a record of that time How is a record of magnetic reversals recorded at mid-ocean ridges?

20. $200 Oceanic & Continental What are the two types of tectonic plates?

21. $400 Convergent, Divergent, Transform What are the three types of plate boundaries?

22. $600 Because the atoms move farther away, making it less dense that the surrounding rock Why does hot rock rise?

23. $800 Because oceanic lithosphere is more dense than continental lithoshpere Why does an oceanic plate subduct below a continental plate?

24. $1000 Ridge push & Slab pull Other than convection, what are two possible causes of tectonic plate motion?

25. $200 Normal, Reverse (Thrust), & Strike-Slip What are the 3 types of faults?

26. $400 Reverse or Thrust Fault In what type of fault does the hanging wall move up relative to the footwall?

27. $600 Normal Fault What type of fault occurs because of tension?

28. $800 Left=footwall, Right=hanging wall Look at the fault above, which block is the footwall? Which is the hanging wall?

29. $1000 Anticline What type of fold is shown below?
