A fresh snowfall is a fluffymass of loosely packed snowflakes, small delicate ice crystals grown in the atmosphere. As thesnow ages on the ground for weeks or months, the crystals shrink and become more compact toform firm, a much whole mass becomes squeezed together into a more dense form, granularsnow. As new snow falls and buries the older snow, the layers of granular snow further compactto form firm, a much denser kind of snow, usually a year or more old, which has little porespace. Further burial and slow cementation- a process by which crystals become boundtogether in a mosaic of intergrown ice crystals- finally produce solid glacial ice. In this processof recrystallization, the growth of new crystals at the expense of old ones, the percentage of airis reduced from about 90 percent for snowflakes to less than 20 percent for glacier ice. Thewhole process may take as little as a few years, but more likely ten or twenty years or longer.The snow is usually many meters deep by the time the lower layers are converted into ice. Incold glaciers those formed in the coldest regions of the Earth, the entire mass of ice is attemperatures below the melting point and no free water exists. In temperate glaciers, the ice isat the melting point at every pressure level within the glaciers, and free water is present as smalldrops or as larger accumulations, in tunnels within or beneath the ice. Formation of a glacier iscomplete when ice has accumulated to a thickness (and thus weight) sufficient to make it moveslowly under pressure, in much the same way that solid rock deep within the Earth can changeshape without breaking. Once that point is reached, the ice flows downhill, either as a tongue ofice filling a valley or as thick ice cap that flows out in directions from the highest central areawhere the most snow accumulates. The up down leads to the eventual melting of ice.
