8. What were the two flaws with Wegner’s theory?
How did it support Pangaea?
9. What were the two pieces of important technologies that converted our beliefs from Continental Drift to
Plate Tectonics? How did they demonstrate that it is not only the continents that move?
10. What is a Mid Ocean Ridge and how is it created?
11. What is a trench and how is it created?
12. What were the two things that were revealed about our ocean floor after collecting and investigating rock
samples?
13. What is oceanic crust more dense than continental crust?
14. How is Paleomagnetism related to the AGES of rocks on the ocean floor? How did this support Plate
Tectonics?
