Climbing is the activity of using one's hands, feet, or other parts of the body to ascend a steep topographical object that can range from the world's tallest mountains (e.g. the eight thousanders) to small boulders. Climbing is done for locomotion, for sporting recreation, for competition, and is also done in trades that rely on ascension; such as rescue and military operations. Climbing is done indoors and outdoors, on natural surfaces (e.g. rock climbing and ice climbing), and on artificial surfaces (e.g. climbing walls).
