Seafloor spreading is a geologic process … Webb22 mars 2012 · In 1960, Harry Hess proposed that the movement of the continents was a result of sea-floor spreading. 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? …
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 … 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…
WebbOn each side of the ridge, sea floor moves from the ridge towards the deep-sea trenches, where it is subducted and recycled back into the mantle. A test of the hypothesis of sea …
