In spite of a number of geological and geophysical evidences of an astronomical influence, Earth's rotation has usually been neglected in the origin of plate tectonics. We show that the westward drift of the lithosphere and ultimately plates fragmentation and interactions are feasible results of the Earth's rotation assuming three coexisting processes: i.e., 1) Earth's rotation is decelerating, mainly due to tidal torques; 2) The downwelling of the denser material toward the bottom of the mantle and in the core opposingly provides an acceleration of the Earth's rotation, partly counterbalancing the tidal drag; 3) The decoupling at the base of the lithosphere occurs over a convective underlying mantle, with ferromagnetic properties, (both phenomena decrease relative friction).
