What layer of Earth is made of mostly solid iron?
Inner Core
200
What do you call the area where two tectonic plates meet?
Plate Boundary
200
What happens when a continental plate converges with a continental plate?
Their densities are similar and result in both plates pushing upward into mountains
200
What type of boundary is made when two tectonic plates collide?
Convergent

What hardens to form new rock at mid-ocean ridges?

The type of tectonic plate boundary that sometimes has a subduction zone is ______.
Convergent Boundary

Why did geologists not believe Wagener's theory of Continental Drift?

He could not explain what force caused the plates to move (convection currents)
