Plate Tectonics

Front

What causes the movement of Earth's tectonic plates?

Back

Convection currents.

Front

What is a location where two tectonic plates collide called?

Back

Convergent boundary.

Front

True or False: The continental plates move so quickly that we can feel them.

Back

False.

Front

Which layer of Earth flows slowly and causes the crust to move?

Back

Mantle.

Front

What does sea-floor spreading explain?

Back

New crust is created at a divergent boundary.

Front

What are the three types of tectonic plate boundaries?

Back

Divergent, Convergent, and Transform boundaries.

Front

What is the process called when tectonic plates move apart?

Back

Divergence.

Front

What geological feature is commonly formed at convergent boundaries?

Back

Mountains or deep ocean trenches.

Front

What is the significance of the asthenosphere in plate tectonics?

Back

It is the semi-fluid layer of the mantle that allows tectonic plates to move.

Front

What is a transform boundary?

Back

A boundary where two tectonic plates slide past each other.
