Alfred Wegener was born in Berlin on 1 November 1880, the youngest of five children, to Richard Wegener and his wife Anna. His father was a theologian and teacher of classical languages at the Joachimsthalschen Gymnasium [ 6 ] and Berlinisches Gymnasium zum Grauen Kloster .
The German Greenland Expedition (German: Deutsche Grönlandexpedition), also known as the Wegener Expedition, was an expedition to Greenland in 1930–1931. It was led by German scientist Alfred Wegener (1880–1930), who had previously taken part in two other ventures to Greenland.
Continental drift is the 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, 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 ...
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.
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).

Ernst Sorge was a member of Alfred Wegener's expedition. Together with Johannes Georgi he stayed in Eismitte from July 1930 to August 1931. Fritz Loewe stayed from October 1930 to May 1931. Sorge hand-dug a 15 m deep pit adjacent to his subterranean snow cave, which served as living quarters during the seven-month-long overwintering.
Alfred Wegener first proposed in 1915 that continents had once been joined together and had since moved apart. [ 6 ] [ 7 ] Although he produced an abundance of circumstantial evidence, his theory met with little acceptance for two reasons: (1) no mechanism for continental drift was known, and (2) there was no way to reconstruct the movements of ...
