Seafloor spreading typically occurs at a rate of about 2 cm per year. This slow movement of the oceanic crust results from the upwelling of magma at mid-ocean ridges, which pushes the plates apart and adds new crust to the seafloor. The rate of seafloor spreading can vary depending on the specific location and the geological context.
