Boundaries that slide past one another.

• Divergent

• Convergent

• Transform

This volcano gathers magma deep within the Earth’s surface.

It explodes violently.

Grows thousands of meters tall.

• Cinder Cone

• Composite

• Shield

• Lava Dome

The pieces of land that connect together on the Earth's outer shell.

• Boundary

• tectonic plates

• volcanoes

• caldera

Tectonic plates collide into each other and mountains can form.

• Transform

• Divergent

• Convergent

One plate moves under another one and a volcano can form. 

• Divergent boundary

• Subduction

• Transform boundary

An active volcano that is not erupting at that moment is...

• Active

• Dormant

• Extinct

A large volcanic crater that is formed after the magma chamber collapses.

• Shield Volcano

• Hot Spot

• Caldera

• Subduction

This volcano has not erupted for at least 10,000 years and is not expected to erupt again for the same amount of time.

• Active

• Dormant

• Extinct

• Subduction

What you call magma once it comes out of an erupting volcano.

• caldero

• lava

• mantle

• convection current

What is vent?

• It is magma that reaches Earth's surface.

• It is any opening at the Earth's surface through which magma erupts or volcanic gases are emitted.

• It is built from particles and blobs of congealed lava ejected from a single vent.
