continental drift definition. A term, no longer used by geologists, that refers to the fact that continents are not stationary, but move across the Earth's surface. Continental drift is one feature of the modern theory of plate tectonics. (See Pangaea.)
THE THEORY OF CONTINENTAL DRIFT. The drifting of tectonic plates is an on-going process that has changed the configuration of the continents since their formation in Archean time. This hypothesis first proposed in 1912 by Alfred Wegener, a German Meteorologist, was not widely accepted until after 1960.Wegener's evidence for continental drift includes:he drifting of tectonic plates is an on-going process that has changed the configuration of the continents since their formation in Archean time.
