Although many people do not think about Ice as a mineral, it is in fact a mineral just as much as Quartz
is. It is a naturally occurring compound with a defined chemical formula
and crystal structure
, thus making it a legitimate mineral. The only consideration not to consider it a mineral is the fact that it is not stable at room temperature.
All Ice is colorless, unless impure. Flaws and cracks cause it to be white. Snow is colorless, but the reflections of its crystal sides cause it to appear white. Snow has a most interesting crystal form. Each one forms with hexagonal
shapes, often with intriguing and interesting shapes. No two Snow crystals are alike. Snow crystals cling together to form snowflakes.
Hailstones are formed in thunderclouds, where small water particles are tossed about from the wind, accumulating layers of Ice. When the Hailstones get heavy and can no longer remain suspended in a cloud, they fall to the earth. Hailstones up to 5 inches (13 cm) in diameter have fallen in certain regions.
Glaciers are formed when snow fails to melt and accumulates, and eventually starts "flowing" downhill like a river. When a moving glacier reaches a body of water, it forms Icebergs, or floating "mountains" of compressed snow.
