CONTINENTALDRIFT
Continental drift
Continental drift is the movement of the Earth's continents relative to each other by appearing to drift across the ocean bed. The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596. The concept was independently and more fully developed by Alfred Wegener in 1912. The theory of continental drift was superseded by the theory of plate tectonics, which explains how the continents move.The above text is a snippet from Wikipedia: Continental drift
