The German polar researcher, geophysicist and meteorologist Alfred Wegener found evidence that the continents were joined together at one time. He proposed the theory of continental drift according which the Earth's continents move and float somewhat like icebergs in water. He also stated that continents move up and down to maintain equilibrium in a process called isostasy.
