Earth's mantle depth

WebBelow the Aleutian island arc, at depths of 100 to 120 kilometers, water is forced out of the subducted Pacific plate. This water lowers the melting point of the overlying mantle, causing it to melt. The melting forms magma, which rises to feed the 55 currently active volcanoes that make up the island arc. © AMNH
