Age of oceanic crust; youngest (red) is along spreading centers. Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.Seafloor spreading helps explain continental drift in the theory of plate tectonics.he destruction of oceanic crust occurs at subduction zones where oceanic crust is forced under either continental crust or oceanic crust. Today, the Atlantic basin is actively spreading at the Mid-Atlantic Ridge. Only a small portion of the oceanic crust produced in the Atlantic is subducted.
Convergence supports the theory of seafloor spreading. Samples of the deep ocean floor are evidence of seafloor spreading because the basaltic oceanic crust and overlapping s â¦ ediment become younger as the mid-ocean ridge is approached.Also, the rock that makes up the floor of the ocean is younger than the continents.amples of the deep ocean floor are evidence of seafloor spreading because the basaltic oceanic crust and overlapping s â¦ ediment become younger as the mid-ocean ridge is approached.
