Back

A large depression in the Earth's surface that holds ocean water.

Back

An opening in the Earth's crust through which molten lava, ash, and gases are expelled.

Front

supervolcano

Back

A volcano that has had an eruption of magnitude 8 on the Volcano Explosivity Index, capable of producing massive eruptions.

Front

transform plate boundary

Back

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

Front

earthquakes

Back

Sudden shaking of the ground caused by the movement of tectonic plates.
