WebNew oceanic crust is formed when the seafloor spreads as hot molten rock (magma) wells up into the rifts of the mid ocean ridge. What happens to older oceanic crust as new rock … WebMidocean ridges are the gaps that occur between tectonic plates. The gaps in the plates allow the magma within the Earth to spill out and reach the surface, which creates new ocean crust and displaces the old crust, pushing the plates apart. Meanwhile, subduction zones are where tectonic plates meet one another.
