Continental drift is the 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 they ride on plates of the Earth's lithosphere.
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.
Pangaea or Pangea (/ p æ n ˈ dʒ iː ə / pan-JEE-ə) [1] was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. [2] It assembled from the earlier continental units of Gondwana , Euramerica and Siberia during the Carboniferous approximately 335 million years ago, and began to break apart about 200 million years ...
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 its Mysteries Unveiled").
This theory was launched by Arthur Holmes and some forerunners in the 1930s [21] and was immediately recognized as the solution for the acceptance of the theory as originally discussed in the papers of Alfred Wegener in the early years of the 20th century. However, despite its acceptance, it was long debated in the scientific community because ...
Although Wegener's theory was formed independently and was more complete than those of his predecessors, Wegener later credited a number of past authors with similar ideas: [18] Franklin Coxworthy (between 1848 and 1890), [19] Roberto Mantovani (between 1889 and 1909), William Henry Pickering (1907) [20] and Frank Bursley Taylor (1908).

Alfred Wegener, around 1925 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 ...
Alfred Wegener spearheaded the original theory of continental drift and spent much of his life devoted to this theory. He proposed "Pangaea", one unified giant continent. [9] During the development of continental drift theory, there was not much exploration of the
