Epeirogeny refers to broad, gentle uplifts or subsidence of large areas of the Earth’s crust, typically not associated with volcanic or seismic activity. These vertical movements can create plateaus, basins, and other large-scale landforms. Epeirogeny is important in understanding long-term landscape evolution, tectonics, and sedimentary basin development.
