... As the seafloor spreads apart, magma moves upward and flows from the cracks. It becomes solid as it cools and forms new seafloor. As new seafloor moves away from the ridge, it cools, contracts, and becomes denser than the material below it. This dense, colder seafloor begins to sink, helping to for ...
