Plate Tectonic

Alfred Wegener believed that all of the continents were once joined in one landmass called it Pangae. What was his theory called?

• Oceanic Drift

• Plate Tectonics

• Continental Drift

The process by which oceanic crust sinks beneath continental crust is called:

• Subduction

• Mid-Ocean Ridge

• Boundary
