What was Alfred Wegener's hypothesis for continental drift, and why was his idea not accepted? What is meant by a "spontaneous" reaction? Give some examples. Explain molecular orbital theory. Who discovered this theory? What is the 'Claisen rearrangement'?
Pangaea or Pangea was first proposed by Alfred Wegener in 1912, using fossil evidence to back up his hypothesis of a supercontinent. The name comes from pan or whole and Gaia or Mother Earth. Continental Drift: The continents of the Earth slowly move around due to the convection currents in...

The continental drift theory was based on several factors. One of the arguments, which had been pointed out by others before Wegener, was that some of the continents simply looked like they fit together. Perhaps the most obvious example of this can be seen in the way that the eastern coast...
In 1912, Alfred Wegener proposed the theory of Continental Drift, which suggested that the continents were joined together at a certain time in the past and formed a single landmass known as Pangaea. In accordance with this theory, the shapes of continents and matching coastline geology between ...
In 1912, the German geologist Alfred Wegener proposed that Earth's continents are mobile rafts of lighter crust that have shifted over time by plowing their way through the denser crust of the oceans. The theory, called continental drift, was partly motivated by the apparent fit, like puzzle ...
German meteorologist and geophysicist Alfred Wegener was the first person to formulate a complete statement of the continental drift hypothesis. Previous scientists had explained the separation of the modern world’s continents as having resulted from the subsidence, or sinking, of large portions of an...

Alfred Wegener, starting in 1912, was the first scientist to discuss supercontinents seriously, as part of his theory of continental motion. He combined a body of new and old evidence to show that the Earth's continents had once been united in a single body, back in late Paleozoic time. ...
