'''Volcanoes''' are formed along 2 different types of [[Tectonic Plate Margin|tectonic plate margin]]; [[Destructive Plate Margin]]s and [[Constructive Plate Margin]]s.
At [[Destructive Plate Margin]]s more [[dense]] [[Oceanic Plate|oceanic plate|Oceanic Plate]] moves under the less [[dense]] [[Continental Plate|continental plate]]. As this happens the [[Oceanic Plate|Continental Plateoceanic plate]] is melted and a lot of [[magma]] forms. This [[magma]] then rises towards the surface of the [[crust]] through cracks in the [[crust]] called [[vents]]. As this [[magma]] reaches the surface it creates a [[Volcanic Eruption]] due to high [[pressure]] being relased and a volcano is formed.
