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:

plate movement

California

San Andreas Fault Line

TRANSFORM BOUNDARY

Convection currents are responsible for...plate movement

Where does the energy come from that creates this movement? mantle This process can cause:

mid-ocean ridge and volcano

Process of Sea-Floor Spreading

near plate boundaries

Earthquake waves are also called

Earth Layers

seismic waves

matching fossils provides evidence for...

Africa and South America might have been connected

What can happen at a boundary that causes an earthquake?

it can MOVE
