WebAs the subducted oceanic plate sinks and heats up, water is gradually released from the sediments and minerals within the plate ‘slab’. Water has the effect of reducing the melting temperature of the mantle by about 60–100°C. It is this process that allows the generation of magma at depth that feeds volcanoes that are formed at the surface.
