Seafloor spreading. 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.eafloor spreading helps explain continental drift in the theory of plate tectonics. When oceanic plates diverge, tensional stress causes fractures to occur in the lithosphere.
Sea-floor spreading occurs where oceanic plates are diverging from one another. Plates are huge slabs into which the crust as well as the upper part of the mantle (the intermediate zones between the Earthâs crust and core) is divided.As the plates move apart, the rocks break and form a crack between the plates.s a result, the age of the rocks increases as one move away from the rift-zone (place where the earthâs crust is pulled apart). The mid-oceanic ridge is the primary site for sea-floor spreading. Earthquakes and volcanoes are where sea-floor spreading occurs.
