Abstract : Many geologists have devoted their investigations of recent movements of the earth's crust, and to the morphological expressions of these movements. The knowledge of the causes of the tectonic movements of the earth's 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 earth's 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 earth's 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 earth's 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 earth's crust and in its upper mantle. (Author)
