This is the meteorologist who first proposed the Theory of Continental Drift
Who is Alfred Wegener?
200
These features form as new crust rises to the surface during seafloor spreading

200

This is where convection currents take place.

What is the mantle?

200
This type of plate boundary involves two plates moving toward each other.
