Hill
landform that extends above the surrounding terrain in lower mountain ranges, smaller than a mountain
A hill is a landform that is higher than the surrounding terrain and that is smaller than a mountain. Hill is a highland of much lower elevation than a mountain. Normally it is not as steep as a mountain. By definition, a hill is often described as being lower than 600 meters (about 2,000 feet). However, some definitions say a hill is lower than 300 meters (about 1,000 feet). The surface of a hill is much more stable than that of a dune. Hill have long been used for hill forts
