PLATE BOUNDARIES
The study of earth’s plate movement is called _________________________

Which two continents look like they best fit together? ______________________________________________________
Why was Wegner’s Theory of Continental Drift not accepted?
List the 3 types of plate boundaries. _____________________________________________________________________
Explain the two types of convergent plate boundaries. ______________________________________________________
What type of features do we see when continental –continental convergence takes place?
What type of features do we see when oceanic – continental convergence takes place?
At an ocean-ocean convergence, would the volcanic islands form on the subducting plate or the overriding plate? (Circle)
What happens to the age of rocks as you move away from a mid ocean ridge?
What have we learned about Earth’s magnetic poles from studying mid ocean ridges?
If you look at the left side of a mid-ocean ridge and then look at the right side of the same ridge, what might you notice?
(think about the sea floor spreading lab)
Which plate boundary is responsible for the mid ocean ridge? Which way are the plates moving? ___________________
