The prairies are flat primarily due to their geological history and the processes of erosion and sediment deposition. Over millions of years, wind and water have worn down the land, smoothing out hills and valleys. Additionally, the region's soil composition and the lack of significant geological activity, such as tectonic uplift, contribute to its flat topography. This flatness facilitates the growth of grasses and other vegetation typical of prairie ecosystems.
