The hypothesis of continental deep subduction and rapid exhumation has been of much controversy, since it was put forward two decades ago. It is known that the continental deep subduction needs mantle convection to drag, but the fact of observed continental roots and the physical evidence of slow growth of large diamond particles at fixed depth during three billion years in the upper mantle suggest no occurrence of a largescale mantle convection. The mainstream current tectonic theory is essentially a heat engine theory, which explains that the driving force of the heat engine is the mantle convection. So, it is necessary now to get rid of this theory framework and take up the rotating machine theory as a guide to approach to the geotectonics. According to the law of conservation of energy, the author holds that tidal action may serve as the driving force, which can transform the earth rotation energy into the tectonic motions on the basis of the rotating machine theory. The global tectonic movement is the response to tidalinduced crust—mantle interaction.
