Volcanoes

1) Volcanoes are caused by movement of tectonic plates. At destructive plate margins the oceanic plate goes under the continental plate because it's more dense- this also creates an ocean trench:

- The oceanic plate moves down into the mantle, where it's melted and destroyed.

- A pool of magma forms.

-The magma rises through the cracks in the crust called vents.
