Alfred Wegener, being a meteorologist, had proposed tidal forces and centrifugal forces as the main driving mechanisms behind continental drift; however, these forces were considered far too small to cause continental motion as the concept was of continents plowing through oceanic crust. O Therefore, Wegener later changed his position and asserted that convection currents are the main driving force of plate tectonics in the last edition of his book in 1929 D However, in the plate tectonics context (accepted since the seafloor spreading proposals of Heezen, Hess, Dietz, Morley, Vine, and Matthews during the early 1960s), the oceanic crust is suggested to be in motion with the continents which caused the proposals related to Earth rotation to be reconsidered.
In more recent literature, these driving forces are: 1)Tidal drag due to the gravitational force the Moon (and the Sun) exert:s on the crust of the Earth 2) Global deformation of the geoid due to small displacements of the rotational pole with respect to the Earth's crust; 3)Other smaller deformation effects of the crust due to wobbles and spin movements of the Earth rotation on a smaller time scale. Forces that are small and generally negligible are: 1.The Coriolis force 2.The centrifugal force, which is treated as a slight modification of gravity
