Where Arc Volcanoes Form

Volcanic arcs form at convergent plate boundaries, where one tectonic plate subducts beneath another. As the subducting slab descends into the mantle, water released from it lowers the melting point of the overlying mantle wedge, producing magma that rises and erupts to build a chain (or arc) of volcanoes on the overriding plate.
