A steep-walled valley created by a river or stream is known as a canyon or gorge. These formations occur through the erosive action of flowing water over long periods, carving deep channels into the surrounding rock and soil. The resulting landscape features steep cliffs and often dramatic scenery, showcasing the power of natural forces in shaping the earth's surface. Examples include the Grand Canyon in the United States and the Colca Canyon in Peru.
