The 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.
The development of the theory of plate tectonics was the scientific and cultural change which occurred during a period of 50 years of scientific debate. The event of the acceptance itself was a paradigm shift and can therefore be classified as a scientific revolution, [47] now described as the Plate Tectonics Revolution.
The theory of continental drift has since been validated and incorporated into the science of plate tectonics, which studies the movement of the continents as they ride on plates of the Earth's lithosphere. [2] The speculation that continents might have "drifted" was first put forward by Abraham Ortelius in 1596.

He considered seafloor spreading at divergent plate boundaries as an effect of it. [26] In his opinion mantle convection as used as a concept in the theory of plate tectonics is physically impossible. His theory includes the effect of solar wind (geomagnetic storms) as cause for the reversals of the Earth magnetic field. The question of mass ...
Plates in the crust of the earth, according to the plate tectonics theory. In the general case, seafloor spreading starts as a rift in a continental land mass, similar to the Red Sea-East Africa Rift System today. [16] The process starts by heating at the base of the continental crust which causes it to become more plastic and less dense.
This confirmation of Alfred Wegener's theory of continental drift strengthened the proposal of a single, ancient land mass, which is called Pangaea. The samples gave further evidence to support the plate tectonics theory, which at the time attempted to explain the formation of mountain ranges, earthquakes, and oceanic trenches. [6]
“Alternatively, it could be the result of mantle-driven processes similar to plate tectonics, but which ended quite early on in Mars’ history.” There is evidence for and against both ...
