He hypothesized that the sea-floor was spreading from vents in the Great Global Rift, where hot magma oozed up. As the magma cooled it forced the existing sea-floor away from the Rift on either side. What Goes On At Mid-Ocean Ridges? … can high alkaline water cause diarrhea

"Seafloor 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. Plates that are not subducting are driven by gravity sliding off the elevated mid-ocean ridges a process called rid… " - The process of sea-floor spreading

WebbThe process of seafloor spreading happens at mid-ocean ridges, where new oceanic crust is generated by volcanic activity and then progressively travels away from the ridge. … 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.
