How does new ocean crust form
WebNew oceanic crust is formed at mid-ocean ridges, where the ocean floor is spreading apart. Oceanic crust is broken down in regions called subduction zones. The plates in a subduction zone move toward each other so that one of the plates descends beneath the other Salt water: Ocean water is salt water containing a variety of salts. 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 is formed? As old oceanic crust is subducted and melted into magma, new oceanic crust in the form of igneous rock is formed at mid-ocean ridges and volcanic hotspots. …
