How Volcanoes are Formed

Volcanoes form when an oceanic plate collides with a continental plate. The oceanic plate subducts under a continental plate, since it is denser, forming a volcano. These volcanoes are also formed by convergent plate boundaries, since they are the plate boundaries that collide. Something unusual about Hawaii though, is that it has hotspot volcanoes meaning they do not form with convergent plate boundaries. Hot spot volcanoes are formed from divergent plate boundaries and are formed by pressure. They have deep crusts, are like blow torches, are warmer in temperature, and are especially hotter in the convection cell.
