Heat flow from the earth’s interior depending on inner parameters variations

The approximate equality of heat flows on the land and the ocean; high heat flow values on the middle oceanic ridges; a relationship of heat flow with age of tectogenesis; the extremely low heat flow values are considered as main evidence for any theoretical explanation. The deviation of surface heat flow from its equilibrium value is considered. Computing analysis of high temperature heat transfer coefficients is given. Some aspects of numerical techniques of the thermal history of the Earth are discussed. The influence of sudden and gradual formation of the Earth Crust on the surface heat flow is considered.
