Oceanic crust is continuously being created at mid-ocean ridges<span>. As plates diverge at these </span>ridges<span>, magma rises into the upper mantle and crust. As it moves away from the </span>ridge<span>, the lithosphere becomes cooler and denser, and sediment gradually builds on top of it.</span>
