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.
Â· just now. Report Abuse. Seafloor spreading occurs at tectonically divergent plate boundaries, where, not surprisingly, the plates are moving apart (diverging). Earth's system takes place along the Mid-Ocean Ridge, which, in its entirety, is 80,000 km (49,700 mi) long.eafloor spreading occurs when two tectonic plates are moving apart from each other. Magma rises, and new Earth crust is formed. It is occurring all the time.
