WebIsland arc volcanoes occur when one plate descends, or subducts, under another plate. Subduction allows water from the subducting plate to be driven upward, off the subducting plate and into the mantle wedge. This lowers the melting point of the mantle, and it melts to form magma. This magma will rise and leak into the crust forming a volcano. Web30 mrt. 2024 · An island arc is a chain or group of islands that forms from volcanic activity along a subduction zone. Subduction occurs when oceanic lithosphere sinks underneath continental or oceanic lithosphere. The sinking rock melts into the magma in the asthenosphere and some comes to the surface, forming volcanoes. read id ncWebIsland arcs form on the crest of curved crustal ridges bounded on one side by deep oceanic trenches.
