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.
Because of global warming and climate change the glaciers around the globe are rapidly melting.....with the rapid melting of land ice there will be changes in the sea levels i.e., there will be rise in the sea levels .with the rise in sea level the low lying areas,islands will be submerged under the water.reas affected will be those that depend on water emanating from ice glaciers. During the dry seasons there will be a shortage of fresh water from ice glaciers, making the land dry and unsuitable for agriculture.
