Annotation:  In the article, on the basis of known facts about the horizontal movement of lithospheric plates and the dynamics of changes in the relief of the surface of the Earth, the question of the collision of plates – a collision – was considered. That is, the reconstruction of a natural phenomenon – the mechanical interaction of lithospheric plates in time. The process of mechanical interaction of lithospheric plates is accompanied by the formation of mountain complexes due to vertical deformations of the Earth's surface. A mathematical model has been developed to determine the dynamics of changes in the terrain of the Earth’s surface on the basis of the energy conservation law. Depending on the speed of horizontal displacements of lithospheric plates, their physicotechnical properties, formulas were obtained for determining the relative and absolute vertical deformations of the Earth’s surface over time. Numerical calculations were carried out to determine vertical deformations in the area of the Alps, Caucasus Mountains, Ural Mountains, Pamir mountains. The calculated values of the rate of vertical deformations of 0.0053–0.027 mm per year coincide with the data of A.V. Peive. Mathematical and numerical analysis of the obtained formulas indicates their validity. These studies can be used to predict the magnitude of the vertical tectonic movements of the Earth's surface in areas of collision of lithospheric plates.

Keywords:  relief of the Earth's surface, tectonic movement, lithospheric plates, collision, mountain structures, energy conservation law, formulas, vertical deformations, legitimacy.
