Geography:
Be able to provide a real-world geographic example for each type of plate boundary
Review Questions:
The boundary between crust and mantle is defined by a change in rock type, how do we recognize the
boundary between the lithospheric and asthenospheric mantle?
Provide the name of a plate that carries only oceanic crust
What are the 6 different types of plate boundaries?
Provide an actual geographic example for each of these boundaries
What two plates laterally “transform relative to one another” along the west coast of California?
Explain how you can tell the difference between left-lateral and right-lateral motion.
How was Arthur Holmes’ convection current hypothesis wrong?
Explain and discuss the major forces responsible for plate motion?
What happens to subducted slabs?
