Seafloor spreading is the theory that explains how new ocean crust is formed at a divergent boundary because of the upwelling of magma from the mantle that creates new oceanic lithosphere as tectonic plates pull apart. As the plates separate, magma rises to fill the gap, solidifying to form new crust. This process gradually pushes older crust away from the ridge, leading to the creation of new ocean floor.
