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.
In November 1926 Wegener presented his continental drift theory at a symposium of the American Association of ... on 12 May 1931, Wegener's skis were discovered.
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").
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]

Wilson was born in Ottawa on October 24, 1908, the son of John Armistead Wilson CBE, and his wife, Henrietta Tuzo. [4] Wilson's father was of Scottish descent and his mother was a third-generation Canadian of French descent.
Alfred Wegener (German, 1880–1930) – developed theory of continental drift; Frank T. M. White (Australian, 1909–1971) – mining and metallurgical engineer; mineral science educator; Emil Johann Wiechert (German, 1861–1928) – first verifiable model of layered structure of the Earth; pioneering work on propagation of seismic waves
In 1889 and 1909 Roberto Mantovani published a hypothesis of Earth expansion and continental drift. He assumed that a closed continent covered the entire surface of a smaller Earth. Thermal expansion caused volcanic activity, which broke the land mass into smaller continents. These continents drifted away from each other because of further ...
