The sediment will pack together with other sediment and eventually harden into rock.
Arctic Ocean, Atlantic Ocean and Pacific Ocean
The magma forming stratovolcanoes rises when water trapped both in hydrated minerals and in the porous basalt<span> rock of the upper oceanic crust is released into </span>mantle<span> rock of the </span>asthenosphere<span> above the sinking oceanic slab. The release of water from hydrated minerals is termed "dewatering", and occurs at specific pressures and temperatures for each mineral, as the plate descends to greater depths. The water freed from the rock lowers the </span>melting point<span> of the overlying mantle rock, which then undergoes partial melting and rises due to its lighter density relative to the surrounding mantle rock, and pools temporarily at the base of the </span>lithosphere<span>. </span>
