The theory of continental drift and plate tectonics
Alfred Wegener
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. The idea was rejected at first as he was a Meteorologist and not regarded as a proper scientist.
Alfred Wegener studied volcanoes. He was a German scientist who proposed the idea of the continental drift.
