When a car is moving it has kinetic energy. When a car is sitting on top of a hill it has potential energy. By hitting the brakes, that kinetic energy is absorbed by the brake pads via friction and converted into heat energy. The friction of the tires is also what provides for turning.
Glaciers change the surface of the land in several ways. By pushing rocks and gravel along with its encroachment a glacier leaves that material behind when it retreats. Most glaciers have water melting out of them when it gets above freezing. That water erodes the landscape forming streams and rivers.
Simply stated, a glacier is a large, slow-moving mass of ice. While there are many types of glaciers, they can be divided into two categories: alpine and continental. Alpine glaciers are found in a mountainous region and flow down valleys.Continental glaciers are dome-shaped glaciers that flow away from a central region and are largely unaffected by the landâs topography. The Greenland and Antarctic ice sheets are examples of continental glaciers.Smaller masses of ice, called ice caps, are also considered continental glaciers. Alpine glaciers are further classified by their shape as well as the surface they flow onto.lpine glaciers flow down valleys, and continental glaciers flow outward in all directions from a central point. Glaciers move by two mechanisms: internal deformation and sliding. Internal deformation occurs when the enormous mass of a glacier causes it to spread out due to gravity.
