The process of sea-floor spreading
WebbThe questions in this online quiz will test you on some facts about sea floor spreading. Some points you'll be tested on include tectonic plates and how sea floor spreading … WebbThis “recycling” process, later named “seafloor spreading,” carries off older sediment and fossils, and moves the continents as new ocean crust spreads away from the ridges. Supporting Wegener’s theory of continental drift, Hess explained how the once-joined continents had separated into the seven that exist today.

WebbThis process, called sea-floor spreading, continually adds new material to the ocean floor. Scientists have found strange rocks shaped like pillows in the central valley of mid-ocean ridges. Such rocks can form only if molten material hardens quickly after erupting under water. The presence of these rocks supports the theory of sea-floor spreading.

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.
