A: The three primary causes for tectonic plate movement are the convection of material in the mantle, gravity and the rotation of the planet. These forces cause each of the seven major plates and numerous other microplates to move independently of the others at a rate of a few centimeters per year.
As it has already been explained new crust is formed in zones of spreading. Since this crustal for mation is a continuous process, the new crust pushes the earlier ones from the ridge crest and causes spreading of the lithosÂ­pheric plate. This process is believed to cause plate motion. 2. Oceanic-topography. As the mid-oceanic ridges, from where new lithospheric plates originate, are normally 2 to 4 kms above the level of the ocean floor and slope away more or less symmetrically from the crest, it is thought to be responsible for plate motion. 3. Rate of Motion
