  2. Continental drift - Wikipedia

    en.wikipedia.org/wiki/Continental_drift

    Continental drift is a highly supported scientific theory, originating in the early 20th century, that Earth's continents move or drift relative to each other over geologic time. [1] 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 ...

  3. Pangaea - Wikipedia

    en.wikipedia.org/wiki/Pangaea

    The concept that the continents once formed a contiguous land mass was hypothesised, with corroborating evidence, by Alfred Wegener, the originator of the scientific theory of continental drift, in three 1912 academic journal articles written in German titled Die Entstehung der Kontinente (The Origin of Continents). [11]

  4. Vine–Matthews–Morley hypothesis - Wikipedia

    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.

  5. Plate tectonics - Wikipedia

    This was immediately followed by a symposium on continental drift in Tasmania in March 1956 organised by S. Warren Carey who had been one of the supporters and promotors of Continental Drift since the thirties [66] During this symposium, some of the participants used the evidence in the theory of an expansion of the global crust, a theory which ...

    Heezen was initially unconvinced as the idea would have supported continental drift, then a controversial theory. Many scientists, including Heezen, believed that continental drift was impossible at the time. Instead, for a time, he favored the Expanding Earth hypothesis, [20] [21] (now infamously) dismissing her explanation as "girl talk". [22]

    In 1858, Snider-Pellegrini made these two maps. They depict his interpretation of how the American and African continents may once have fit together before becoming separated. Antonio Snider-Pellegrini (1802–1885) was a French geographer and geologist who theorized about the possibility of continental drift , anticipating Wegener's theories ...

    So that Émile Argand (1916) speculated that the Alps were caused by the North motion of the African shield, and finally accepted this reason 1922, following Wegener's Continental drift theory (Argand 1924 as Staub 1924). Otto Ampferer in the meantime, at the Geological Society Meeting in Vienna, held on 4 April 1919, defended the link between ...

  9. Alfred Wegener - Wikipedia

    en.wikipedia.org/wiki/Alfred_Wegener

    Alfred Wegener has been mischaracterised as a lone genius whose theory of continental drift met widespread rejection until well after his death. In fact, the main tenets of the theory gained widespread acceptance by European researchers already in the 1920s, and the debates were mostly about specific details.
