As the sediments subduct, the water rises into the overlying mantle material and lowers its melting point. Melting in the mantle above the subducting plate leads to volcanoes within an island or continental arc.
Why do volcanoes form at subduction plates?
A subduction volcano forms when continental and oceanic crust collide. The oceanic crust melts and migrates upwards until it erupts on the surface, creating a volcano.
Why do most volcanoes occur at plate boundaries?
Most earthquakes and volcanoes occur because of the movement of the plates, especially as plates interact at their edges or boundaries. ... Volcanoes also form as magma rises upward from the underlying mantle along the gap between the two plates.
