WebJan 24, 2024 · Plate tectonics is the study of how the Earth's crust is shaped by geological forces. It relies on the understanding that the crust is divided into large pieces, or plates, that sit on the molten magma present below the surface. Currents within the interior cause the plates to move, which causes many different geological events, including earthquakes … WebFlake Tectonics. a model of a planetary interior, particularly Venus, in which a thin crust remains stationary but wrinkles and flakes in response to interior convection currents.
