The rise in temperature with depth

That explanation is now accepted by almost all geologists: community events, and high temperature of the internal parts of the Earth, which is proved by volcanoes, are decisive arguments in favor of this view. As for other explanations, none of them can be considered as satisfactory. We do not know of any chemical process, which would have been so common on Earth and would have occurred with such intensity that it can be attributed to an increase in temperature with depth and the melting of large masses of igneous rocks. The same must be said about the transformation of mechanical work into heat. You can probably point to the orogenic processes, but in this case would have been zamechaemy significant differences between the geothermal features of the newest mountain ranges, what are the Alps and the plains, where these processes have not acted. In fact, this is not observed, yes, finally, and this source would be insufficient for the formation of such huge amounts of heat. With regard to the hypothesis that the passage of the Earth and the entire solar system through the warmer regions of the world community, it is unlikely, and you can look for the causes of the phenomenon. But this hypothesis, we will not parse: it now has almost no supporters. Tried to prove that the change of geothermal degrees with depth does not match the fact of the gradual cooling of the Earth from a molten state. To more clearly imagine it, we turn to the properties of the heated and cooling mass. The main issue here is whether the increase geothermal degrees toward the center, or decrease, ie, whether the slower growth in the depths of warmth, or accelerated, and if we find on the surface of the geothermal degrees 33 m, then will it be at a greater depth 34 m, etc. Simple argument eliminates any misunderstandings: a hot body, located in a cold environment, loses its heat, the process returns the latter should be performed more intensively on the body surface and weaker inside. Therefore, differences in temperature of the upper layer should be larger and the closer to the center - less, in other words, growth will slow down the heat: geothermal degrees of the Earth will increase with depth.
