WebOne platecontaining oceanic lithosphere descends beneath the adjacent plate,thus consuming the oceanic lithosphere into the earth's mantle. This on-going process is called … WebVolcanoes form here in two settings where either oceanic plate descends below another oceanic plate or an oceanic plate descends below a continental plate. This process is called subduction and creates distinctive types of volcanoes depending on the setting: ocean-ocean subduction produces an island-arc volcano.
