While all of these factors can contribute to erosion and sculpting of landforms in deserts, rainfall and running water have the greatest impact over time. This is because water can carve through rock and sediment, creating canyons and other distinct features over millions of years. The other factors can have more immediate effects on the surface, but do not have the same long-term shaping power as water.
