The natural landform characterized by steep cliffs and deep valleys is known as a canyon. Canyons are typically formed by the erosion of rock and soil by a river over time. One of the most famous examples is the Grand Canyon in the United States. These structures often have breathtaking views, showcasing layers of geological history. Canyons provide significant habitats for wildlife and are popular destinations for activities such as hiking and rafting, offering both scenic beauty and outdoor recreation opportunities.
