Which Plate Boundaries Will Volcanoes Occur At?

There are a number of different types of plate boundary.

Destructive plate boundary

A destructive plate boundary is sometimes called a convergent or tensional plate margin. This occurs when oceanic and continental plates move together. The oceanic plate is forced under the lighter continental plate. Friction causes melting of the oceanic plate and may trigger earthquakes. Magma rises up through cracks and erupts onto the surface.

An example of a destructive plate boundary is where the Nazca plate is forced under the South American Plate.
