WebThe process of sea floor spreading as determined by evidence such as parallel magnetic patterns on both sides of mid-ocean ridges is what resulted in the geologic community accepting the concept of continental drift. Before that, there was no mechanism that could explain how an entire continent could be moved around. 5 Gordon Stanger

dws toprente onlineSeafloor spreading helps explain continental drift in the theory of plate tectonics. When oceanic plates diverge, tensional stress causes fractures to occur in the lithosphere. The motivating force for seafloor spreading ridges is tectonic plate slab pull at subduction zones, rather than magma pressure, although there is typically significant magma activity at spreading ridges.
