Webb16 maj 2024 · It was not until the discovery of magnetic reversals on the seafloor in the early 1960s that the theory began to sound plausible again. If brand new ocean crust was being formed at the mid-ocean ridges, then the rocks either side of the ridge should show symmetrical patterns of magnetism.

WebbWhen the concept of seafloor spreading came along, scientists recognized that it was the mechanism to explain how continents could move around Earth’s surface. Like the scientists before us, we will now merge the ideas of continental drift and seafloor spreading into 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… reading of the bands in churchWebbSeafloor spreading is only a part of the process moving continents. New oceanic crust material is sourced from mid-ocean ridges (MORs), but mechanisms such as ”mantle drag” are what is proposed to actually make the plates move. As the plates move apart, more tension is placed on the MOR allowing them to split more and release more crustal … reading of high school dxd fanfiction naruto
