What is canyon definition?

A canyon is a deep ravine or gorge with steep sides that is typically formed by the erosion of water through rock formations over a long period of time. Canyons can range in size from small narrow channels to massive gorges that span hundreds of miles. They are often found in areas with arid or semi-arid climates, where the lack of vegetation and high intensity of rainfall events can lead to the rapid erosion of the landscape. Some of the world's most famous canyons include the Grand Canyon in the United States, the Wadi Rum in Jordan, and the Siq Canyon in Petra. Canyons can be explored by hiking, rafting, or in some cases, driving along scenic routes.
