The theory of continental drift was first put forward by Wegener in 1915, from a growing body of speculation in the century previous. It claimed that continents moved relative to each other to cause mountain building, and originally were all grouped as one supercontinent, given the name Pangea. The theory sustained heated debate until a satisfactory driving mechanism emerged in the 1960's, with concepts of sea floor spreading by convection currents in the earth ‘s mantle proposed by Dietz ( 1961) and forming the basis of a new theory of plate tectonics (Le Pichon,1968).
