Abstract

A new conception of dynamic character is given for the internal constitution of the Earth. The main feature of the conception is that the material composition of the Earth becomes more and more homogeneous within its interior. The Earth's core consists of matter in ultra high-pressure state. This ultraphase state is, however, unstable and, therefore, a steady increase of the Earth's volume is going on.

It is shown, furthermore, that the expansion of the Earth is able to account for the formation of the crust and oceanic basins, the energies of tectonic forces and earthquakes, the origin of deep-focus earthquakes, the periodicity of geological phenomena, the continental drift and mountain building, and is supported also by paleogeographical data.
