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 … 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.

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… WebbSea floor spreading common core activity is a common core activity that helps students learn about sea floor spreading, ...

As tectonic plates slowly move away from each other, heat from the mantle’s convection currents makes the crust more plastic and less dense. Which is the first step in seafloor spreading?

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.

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.
