Geotectonics is controlled by mechanical processes within Earth crust. The role of Earth heat is considered as secondary in comparison with geotectonic processes due to hidden character if its activity within ancient structures and absence of clear ideas about heat source and conditions of its transfer in the Earth crust, mantle and core. Hydrothermal-magmatic systems within regions of recent volcanism (controlled by heat flows with capacity on one-two orders higher than regional heat flows) transfer Earth heat due to geothermal gradient. Heat transfer by convection within Earth crust and mantle is determined by self-organization expressed by formation of geological structures conducting heat in these conditions. Thus heat energy is transformed in structure-forming mechanical energy expressed in geotectonics. These ideas make obvious priority of geothermal heat against tectonic processes. Such an approach toward geotectonic problems explain role of geothermal heat in evolution of crust of oceans, mobile belts and platforms. It is noticed principal difference of regional heat flow, which is stable and associated with life of Earth core, and pulses of volcanic and tectonic processes reflecting pulses of astrogenic and solar factors. Volcanic cycles show tendency toward global-scale synchroniety. The meaning of anomalous heat flow is changing. This change reflects the existence of pulses of intense tectonic movements and flare-ups of volcanic activity divided by periods of relative quiet regime. Pulses are generated by the Earth’s rotation, which generate centrifugal plate movement. Coincidence of such pulses with different astral and solar variables confirms ties of anomalous heat flow generation with rotation processes.
