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 ...
The granite outcrops of the Seychelles Islands in the central Indian Ocean were amongst the earliest examples cited by Alfred Wegener as evidence for his continental drift theory. [1] Ridge–plume interactions have been responsible for separating a thinned continental sliver from a large continent (i.e. India). [2]
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.
In 1912 Alfred Wegener proposed the theory of continental drift. [36] This theory suggests that the shapes of continents and matching coastline geology between some continents indicates they were joined together in the past and formed a single landmass known as Pangaea; thereafter they separated and drifted like rafts over the ocean floor ...
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 ...
Polflucht (from German, flight from the poles) is a geophysical concept invoked in 1922 by Alfred Wegener to explain his ideas of continental drift. The pole-flight force F P f {\displaystyle F_{\mathrm {Pf} }} is that component of the centrifugal force during the rotation of the Earth that acts tangentially to the Earth's surface.
He wrote a total ten papers on the subject of continental drift [2] Taylor's ideas about continental drift were independently discovered by Alfred Wegener in Germany three years later, in January 1912, and the theory of continental drift is historically often referred to as the "Taylor-Wegener hypothesis," [2] [6] [7] although Taylor himself ...
Antonio Snider-Pellegrini (1802–1885) was a French geographer and geologist who theorized about the possibility of continental drift, anticipating Wegener's theories concerning Pangaea by several decades. In 1858, Snider-Pellegrini published his book, La Création et ses mystères dévoilés ("The Creation and
