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.
Glaciers And Glaciation By definition a glacier is a mass of ice composed of compacted and recrystallized snow that flows under its own weight. This makes glaciers very effective agents of erosion, transportation and deposition of sediment. The two types of glaciers are Valley or Alpine glaciers Continental glaciers.The difference between them is where they flow. Valley glaciers flow in mountain valleys from high to low elevations. Continental glaciers or ice sheets flow over vast unconfined land areas.Valley glaciers are present at high altitude in mountain valleys of Alaska, the Italian Alps and New Zealand.lacial Drift. All sediment deposited by a glacier whether its a valley glacier or continental ice sheet, is called glacial drift. Till: unstratified sediment deposited directly by glacial ice. It is poorly sorted & contains large boulder, pebbles clay-sized particles.
