Frozen water is found on the Earthâs surface primarily as snow cover, freshwater ice in lakes and rivers, sea ice, glaciers, ice sheets, and frozen ground and permafrost (permanently frozen ground). The residence time of water in each of these cryospheric sub-systems varies widely.
A glass of water left in the freezer eventually becomes a glass of ice. Most people know what happens at 0Âº Celsius (or 32 Âº Fahrenheit): Water freezes. When the temperature outside is below freezing, for example, a rain storm may become a blizzard of snow. A glass of water left in the freezer eventually becomes a glass of ice. The freezing point of water may seem like a simple fact, but the story of how water freezes is a little more complicated. In water at the freezing temperature, ice crystals usually form around a dust particle in the water. Without dust particles, the temperature can get even lower before the water turns to ice. In the laboratory, for example, researchers have shown that itâs possible to cool water down to -40Âº C â without producing a single ice cube.
