Ch 3 Plate Tectonics

the process in which molten material adds new oceanic crust

a plate boundary where two plates are moving toward each other

a plate boundary where two plates move away from each other

a plate boundary where two plates move past each other in opposite directions

The hypothesis that the continents slowly move across Earth's surface

sections of lithosphere that move across the asthenosphere, moves oceanic and continental crust

The longest mountain ranges in the world are

This process creates crust

the name of the single landmass that existed about 200 million years ago

a valley that forms on land where two plates move apart

What process causes the motion of the lithospheric plates on the asthenosphere?

a deep line along the ocean floor where oceanic crust slowly sinks back toward the mantle

the preserved remains or traces of an organism that lived in the past

When 2 continental crust pieces collide they make

This process destroys crust

the theory that pieces of the lithosphere are in constant motion, driven by convection currents

Which kind of crust is more dense and will sink?

an undersea mountain chain where new ocean floor is being created

the process when oceanic crust sinks back toward the mantle at a convergent boundary

Which is not a type of evidence Wegener had for continental drift
