Abstract

After the buildup of a steady convective motion in a layer, the topography of its surface is determined only by the displacements of the material particles lying on its surface.

The results suggest that the small-scale convection in the lithosphere, which forms small irregularities in the topography of the Earth’s surface far from the boundaries of the lithospheric plates, is excited by the significant topographical disturbances caused by thrusts occurring at the boundaries of the lithospheric plates due to the large-scale convection in the mantle.
