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, sporting recreation, for competition, and is also done in trades
that rely on ascension, such as construction 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
and climbing gyms).
