A '''destructive plate margin''' is a location where two [[Tectonic Plates|tectonic plates]] are moving towards one another and eventually meet and one is pushed under the other in a process called [[Subduction|subduction]]. ==About Destructive Plate Margins==[[Subduction]] occurs at '''destructive plate margins''' when an [[Oceanic Plate]] and a [[Continental Plate]] meet. Because the [[Oceanic Plate]] is more [[dense]] it is pushed beneath the less [[dense]] [[Continental Plate]]. As the plates move past each other in a [[Friction]] causes the [[Oceanic Plate]] to be melted and destroyed and therefore [[magma]] is created. The [[magma]] in the [[magma chamber]] then rises and [[volcano]]s are often formed.
