Many geologists have devoted their investigations of recent movements of the earths crust, and to the morphological expressions of these movements. The knowledge of the causes of the tectonic movements of the earths crust is important because it will be helpful in decoding the regularities in the vertical motions during remote geological epochs and in the solution of the problem of energy in tectonic processes. It is important to determine whether the latter are a reflection of abyssal processes occurring in the earths crust and the upper mantle, or if they are basically caused by external forces in relation to the earth. This translation is a study of various Soviet scientists data, indicating the relation between thickness of the earths crust and relief elevations. The graphic compiled by R. M. Demenitskaya is especially considered. Graphics compiled by other scientists differ from the considered one only in the regions of great oceanic depths and great elevations of the relief on the land. In order to obtain the data for the comparison, elevations of the earths surface relief were not used. The maximum of the tectonic movements were used because they reflect more accurately the processes in the abyssal layers of the earths crust and in its upper mantle. Author
