Plate Tectonics

Front

What causes tectonic plates to move?

Back

Convection Currents in the Earth's mantle.

Front

What happens at a transform boundary?

Back

Neither plate subducts; they slide past each other.

Front

Where does the heat from convection currents come from?

Back

The Earth's Core.

Front

What happens at an Oceanic-Oceanic convergent plate boundary?

Back

The older, denser plate subducts beneath the younger plate.

Front

In which layer of the Earth do convection currents occur that cause plates to move?

Back

The Mantle.

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 and sinks into the mantle.

Front

What is a divergent boundary?

Back

A tectonic plate boundary where two plates move away from each other.

Front

What is a convergent boundary?

Back

A tectonic plate boundary where two plates collide.

Front

What is the lithosphere?

Back

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