Front

What is subduction?

Back

Subduction is the process where one tectonic plate slides under another due to density differences.

Front

What is a transform plate boundary?

Back

A transform plate boundary is where two tectonic plates slide past each other.

Front

What causes tectonic plates to move?

Back

Tectonic plates move due to the convection of magma in the Earth's mantle.

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates move towards each other, often causing mountains or trenches.

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move away from each other, creating new crust.

Front

What is a fault?

Back

A fault is a fracture in the Earth's crust where blocks of land have moved past each other.

Front

What is an earthquake?

Back

An earthquake is the shaking of the Earth's surface caused by the movement of tectonic plates.

Front

What is a volcano?

Back

A volcano is an opening in the Earth's crust where molten rock, ash, and gases can escape.
