How did Wegener discovered plate tectonics?
Plate tectonic theory had its beginnings in 1915 when Alfred Wegener proposed his theory of “continental drift.” Wegener proposed that the continents plowed through crust of ocean basins, which would explain why the outlines of many coastlines (like South America and Africa) look like they fit together like a puzzle.
What is Alfred Wegener known for?
Wegener was a German meteorologist, geophysicist and polar researcher. In 1915 he published ‘The Origin of Continents and Oceans’, which outlined his theory of Continental Drift. Wegener was a member of four expeditions to Greenland.
How did Alfred Wegener discover the CDT?
He found research on identical fossils on the coasts of Africa and South America, something for which geologists, convinced that the world map was immutable, had offered a more implausible explanation: land bridges that had vanished after permitting animals and plants to travel from one continent to another.
What happened after Alfred Wegener died?
Upon Wegener’s death, leadership of the Greenland expedition passed to his friend Fritz Loewe. Loewe had trained as a lawyer in Berlin, but developed a passion for science and exploration, earning a PhD in physics. He became a meteorologist and understudy to Alfred Wegener.
