Continental drift is the movement of the Earths continents relative to each other, thus appearing to drift across the ocean bed.[1] 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, but his theory was rejected by some for lack of a mechanism (though this was supplied later by Holmes) and others because of prior theoretical commitments. The idea of continental drift has been subsumed by the theory of plate tectonics, which explains how the continents move.[2]
