NASA Learning Objects: Continental Drift

While plate tectonics is a relativily new idea, scientists have been gathering data in support of the Continental Drift theory for a very long time. In 1912, Alfred Wegener and Frank Taylor first proposed the theory that 200 million years ago the Earth had only one giant continent, from which today's continents broke apart and drifted into their current locations. Wegener used the fit of the continents, the distribution of fossils, a similar sequence of rocks at numerous locations, ancient climates, and the apparent wandering of the Earth's polar regions to support his idea.
