Volcanoes form when magma

• changes in composition.

• hardens beneath Earth's surface.

• flows through the crust.

Magma that has a lot of gas will form a volcano

• that erupts violently.

• with gentle slopes.

• whose lava has low viscosity.

Where do most volcanoes erupt?

• along sliding plate boundaries.

• in the middle of tectonic plates

• along divergent plate boundaries
