Abstract
A concept of the Moon devoid of internal energy, sufficient for volcanic and mountain-forming processes, is widely accepted at the present time. Therefore, it is generally assumed that the relief formation of the Moon is due to external actions on its surface. However, such a viewpoint is not sufficiently substantiated. In fact, the history of Earth's relief shows that the period of telescopic observations of the Moon is too short to enable us to observe changes in whole sections of the crust. Catastrophic changes, apart from actions of water and atmosphere, occur on the Earth only in a very restricted area, and the size does not exceed a few kilometres. Therefore, we must not expect on the Moon any sudden changes over an area exceeding appreciably one square second. The reality of such minute effects in the relief could hardly be established on the basis of available cartographic data.
