A deep gorge or ravine is often referred to as a "canyon." Canyons are typically formed through the erosion of rock by rivers over long periods, resulting in steep, rocky walls. They can vary in size and depth and are often characterized by their dramatic landscapes and unique geological features. Famous examples include the Grand Canyon in the United States and the Fish River Canyon in Namibia.
