Plate Tectonics Test

Definition of plate tectonics

• interaction of the Earth's rigid lithospheric plates as they slide slowly over the mantle

• how Pangaea/ Pangea broke apart and moved to current position

• Convection currents = plate tectonics

• land warping

What happens to the crust in each plate boundary?

• Convergent: Come together; destroyed Transform: neither created or destroyed Divergent: Can be created

• Convergent: destroyed Transform: underwent transformation Divergent: come apart

• None of the above

• All of the above
