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
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]
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 ...
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.
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 ...
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 ...
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
