Alfred Wegener's Pangaea Hypothesis ..

However, it was not until 1912 that the idea of moving continentswas seriously considered as a full-blown scientific theory -- called -- introduced in two articles published by a 32-year-old Germanmeteorologist named Alfred Lothar Wegener.

Alfred Wegener actually met his end on one of these expeditions to Greenland.



After 1906 Alfred Wegener participated in several expeditions to Greenland where high altitude air masses were tracked and where the existence of so-called "jet streams" of air at high altitude became scientifically established.

Undaunted by rejection, Wegener devoted the rest of his life to doggedlypursuing additional evidence to defend his theory.

Alfred Wegener proposed the theory of continental drift at the beginning of the 20th century. His idea was that the Earth's continents were once joined together, but gradually moved apart over millions of years.

From circa 1911 Alfred Wegener, after being influenced by a scientific paper he had come acrossthat listed fossils of identical plants and animals found on opposite sides of the Atlantic, began proposing a then most controversial theory which held that the continents of the earth had once been joined together but had drifted apart through a process that he explicitly, by circa 1915 - with the publication of the first edition of , a book outlining Wegener's theory, - seems to have referred to as Continental Drift (actually - in his own mother tongue - as or ).

His brother Kurt remarked that Alfred Wegener’s motivation was to ..

Wegener's inability to provide an adequate explanation of the forcesresponsible for continental drift and the prevailing belief that the earth was solid andimmovable resulted in the scientific dismissal of his theories.In 1929, about the time Wegener's ideas began to be dismissed, Arthur Holmes elaboratedon one of Wegener's many hypotheses; the idea that the mantle undergoes thermalconvection.

What are some flaws in Alfred Wegener's Continental Drift Theory


The idea of continental drift was not accepted easily by the scientific establishment. Even though Wegener assembled many interlocking pieces of evidence to support his ideas, they were so radical that he was often ridiculed. Eventually, however, scientists made more observations, assembling the modern theory of plate tectonics. The above map shows an idealized schematic of the boundaries of the continental plates.

In 1914 Wegener was drafted into the German army during . He was wounded twice and was eventually placed in the Army's weather forecasting service for the duration of the war. In 1915 Wegener published his most famous work, The Origin of Continents and Oceans as an extension of his 1912 lecture. In that work, Wegener presented extensive evidence to support his claim that all of the Earth's continents were at one time connected. Despite the evidence, most of the scientific community ignored his ideas at the time.
