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.
Profile illustrating the shelf, slope and rise. The continental margin is the zone of the ocean floor that separates the thin oceanic crust from thick continental crust.Together, the continental shelf, continental slope, and continental rise are called continental margin. Continental margins constitute about 28% of the oceanic area.arthquakes and volcanic eruptions are common on the west coast of North America, but there are no active volcanoes on the east coast and large magnitude earthquakes are rare. Geologists refer to the west coast as (tectonically) active continental margin and the east coast a passive continental margin.
