Mid atlantic ridge plates involved
WebIn 1961, scientists began to theorize that mid-ocean ridges mark structurally weak zones where the ocean floor was being ripped in two lengthwise along the ridge crest. New magma from deep within the Earth rises easily through these weak zones and eventually erupts along the crest of the ridges to create new oceanic crust.

WebPlate tectonics is the scientific theory explaining the movement of the earth’s crust. It is widely accepted by scientists today. Recall that both continental landmasses and the ocean floor are part of the earth’s crust, and that the crust is broken into individual pieces called tectonic plates (Fig. 7.14). The movement of these tectonic ... WebIn 1962, for instance, the geologist Harry Hess formally proposed the concept that would become known as seafloor spreading. At plate boundaries like the Mid-Atlantic Ridge, he thought, molten rock from deep inside the Earth would upwell to the surface and cool, producing new oceanic crust. Today, Earth scientists accept seafloor spreading as ...
