In 1915, in the first edition of his book, Die Entstehung der Kontinente und Ozeane, written in German, [22] Wegener drew together evidence from various fields to advance the theory that there had once been a giant continent, which he named "Urkontinent " [23] (German for "primal continent", analogous to the Greek "Pangaea", [24] meaning "All ...
Wegener said that of all those theories, Taylor's had the most similarities to his own. For a time in the mid-20th century, the theory of continental drift was referred to as the "Taylor-Wegener hypothesis". [26] [29] [30] [31] Alfred Wegener first presented his hypothesis to the German Geological Society on 6 January 1912. [5]
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
Although it might perhaps seem less impressive to the layman, that evidence was far more convincing to the geologist than was the matching of continental shelves. In the light of his research, du Toit published a review of the stratigraphic and radioisotope evidence from those regions that supported Wegener's ideas, A Geological Comparison of ...
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 ...
[8] [9] Although Alfred Wegener noticed some similarities to his own hypothesis of continental drift, he did not mention Earth expansion as the cause of drift in Mantovani's hypothesis. [10] A compromise between Earth-expansion and Earth-contraction is the "theory of thermal cycles" by Irish physicist John Joly.
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 ...
The Wegener–Bergeron–Findeisen process (after Alfred Wegener, Tor Bergeron and Walter Findeisen []), (or "cold-rain process") is a process of ice crystal growth that occurs in mixed phase clouds (containing a mixture of supercooled water and ice) in regions where the ambient vapor pressure falls between the saturation vapor pressure over water and the lower saturation vapor pressure over ice.
