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.
Several types of stratified deposits form in glacial regions but are not formed directly by the ice. Varves form where lakes are covered by ice in the winter. Dark, fine-grained clays sink to the bottom in winter but melting ice in spring brings running water that deposits lighter colored sands.lacial ice erodes and shapes the underlying rocks. Glaciers also deposit sediments in characteristic landforms. The two types of glaciers are: 1  Continental glaciers are large ice sheets that cover relatively flat ground. 2  These glaciers flow outward from where the greatest amount of snow and ice accumulate.
