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.
But the mountain glaciers have been telling scientists what the West Antarctica glacier disintegration is now confirming: In the coming centuries, more land will be covered by water and more of nature will be disrupted. A full melt would cause sea level to rise 215 feet.During recent ice ages, glaciers expanded from the poles and covered nearly a third of the continents. And in the distant past there were episodes known as Snowball Earth, when the entire planet froze over.hat is because most of the mountain glaciers lie in areas where temperatures are closer to the melting point than they are in Greenland or Antarctica, and so slight warming tips them to melting. Greenland, with 10 percent of the worldâs ice, has enough to raise sea level by 23 feet.
