On the basis of Tharp’s efforts and other new discoveries about the deep … 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… Webb23 juli 2024 · THE THEORY OF SEAFLOOR SPREADING STATES THAT OCEAN RIDGES ARE PLACES WHERE NEW OCEAN CRUST IS FORMED TRENCHES ARE PLACES WHERE IT IS DESTROYED. … THESE DATA ARE CONSISTENT WITH NEW CRUST FROMING AT RIDGES AND BEING DESTROYED AT TRENCHES.

Webb8 juni 2024 · By the 1960s, scientists had amassed enough evidence to support the missing mechanism—namely, seafloor spreading—for Wegener’s hypothesis of continental drift to be accepted as the theory of plate tectonics. Ongoing GPS and earthquake data analyses continue to support this theory. WebbHess’s model was later dubbed seafloor spreading by the American oceanographer Robert S. Dietz. Confirmation of the production of oceanic crust at ridge crests and its subsequent lateral transfer came from an …
