Front

How do divergent plates move?

Back

Away from each other.

Front

What does sea-floor spreading explain?

Back

New crust is created at a divergent boundary.

Front

What feature can be found along a divergent boundary?

Back

Mid-ocean ridge.

Front

What is a tectonic plate?

Back

A large, rigid piece of the Earth's lithosphere that moves and interacts with other plates.

Front

What is the lithosphere?

Back

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

Front

What is a convergent boundary?

Back

A tectonic boundary where two plates collide, often forming mountains or causing subduction.

Front

What is subduction?

Back

The process where one tectonic plate moves under another and sinks into the mantle.

Front

What is a volcanic island arc?

Back

A chain of volcanic islands formed at a convergent boundary, typically where an oceanic plate subducts beneath another oceanic plate.
