WebWhat is Seafloor Spreading? The theory of seafloor spreading states that the Earth’s crust is in a continual state of growth and evolution. It happens as plates on the Earth’s surface move away. The space left behind between the plates is filled with new material, which slowly pushes the plates apart. WebSea-floor spreading — In the early 1960s, Princeton geologist Harry Hess proposed the hypothesis of sea-floor spreading, in which basaltic magma from the mantle rises to create new ocean floor at mid-ocean ridges.
