Plate Tectonics

Front

What causes tectonic plates to move?

Back

Convection Currents in the mantle.

Front

Where do convection currents that cause plate movement occur?

Back

In the Mantle.

Front

What happens at an Oceanic-Oceanic convergent plate boundary?

Back

The older, denser plate subducts.

Front

What happens at an Oceanic-Continental plate boundary?

Back

The oceanic plate subducts.

Front

What occurs at a transform boundary?

Back

Neither plate subducts.

Front

What are tectonic plates?

Back

Large sections of the Earth's lithosphere that move and interact.

Front

What is subduction?

Back

The process where one tectonic plate moves under another plate.

Front

What is a convergent boundary?

Back

A tectonic plate boundary where plates move towards each other.

Front

What is a divergent boundary?

Back

A tectonic plate boundary where plates move apart.

Front

What is the lithosphere?

Back

The rigid outer layer of the Earth, consisting of the crust and upper mantle.
