Plate Tectonics: Test #2 Review

boundary or fault line

What would be a good name for this diagram?

convergent boundary

Why do these plates move?

convection currents

What theory would explain this diagram?

theory of plate tectonics

Why does the oceanic plate move under the continental plate?

oceanic plate is more DENSE What is happening here?

subduction

What are these arrows showing?

Which state has this geologic feature?

Name the fault:
