Webb9 apr. 2024 · New oceanic crust forms at these ridges through seafloor spreading, which pushes the plates apart. These discoveries led to the development of plate tectonics in the late 1960s, which combined the ideas of continental drift and seafloor spreading to provide a comprehensive explanation of lithosphere movement. WebbNamely, seafloor spreading explained that tectonic plates—including continents—move because of convection in Earth’s interior. Thus, instead of needing to move through oceanic crust, as Wegener’s model had suggested, Hess’s model had continents moving with seafloor—as it is created and recycled.
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… http://earthguide.ucsd.edu/eoc/teachers/t_tectonics/p_seafloorspreading.html

WebbThe Vine–Matthews–Morley hypothesis, also known as the Morley–Vine–Matthews hypothesis, was the first key scientific test of the seafloor spreading theory of continental drift and plate tectonics. Its key impact was that it allowed the rates of plate motions at mid-ocean ridges to be computed. costco locations northern ontarioWebbTectonic plates are composed of oceanic lithosphere and thicker continental lithosphere, each topped by its own kind of crust. Along convergent boundaries, subduction carries plates into the mantle; the material lost is roughly balanced by the formation of new (oceanic) crust along divergent margins by seafloor spreading. costco locations near richmond vaWebbPlate tectonics refers to the global system of coupled boundaries along mid-ocean ridges, subduction zones and transform faults on Earth.
