PLATE TECTONICS: BIRTH OF A THEORY

From his observations, Hess developed a hypothesis that contrasted with Wegeners idea of continents pushing through the ocean crust and suggested instead that the continents rode atop a moving mantle. The continents were passive passengers on the moving plates. Hess also recognized that the earth w ...

... According to Wegener, there was a huge supercontinent called Pangea. (Pangea is Greek for “all land.”) About 200 million years ago, it broke into separate continents. The continents then moved apart. Wegener claimed that mountains were formed at the leading edge of the moving continent. He was also ...

the theory of continental drift
... The main reason that Wegener's hypothesis was not accepted was because he suggested no mechanism for moving the continents. He thought the force of Earth's spin was sufficient to cause continents to move, but geologists knew that rocks are too strong for this to be true. It wasn't until 1928 that a ...

Alfred Wegener
Alfred Lothar Wegener (November 1, 1880 – November 1930) was a German polar researcher, geophysicist and meteorologist.During his lifetime he was primarily known for his achievements in meteorology and as a pioneer of polar research, but today he is most remembered as the originator of the theory of continental drift by hypothesizing in 1912 that the continents are slowly drifting around the Earth (Kontinentalverschiebung). His hypothesis was controversial and not widely accepted until the 1950s, when numerous discoveries such as palaeomagnetism provided strong support for continental drift, and thereby a substantial basis for today's model of plate tectonics. Wegener was involved in several expeditions to Greenland to study polar air circulation before the existence of the jet stream was accepted. Expedition participants made many meteorological observations and achieved the first-ever overwintering on the inland Greenland ice sheet as well as the first-ever boring of ice cores on a moving Arctic glacier.
