Ice is WATER frozen into the solid state. Usually ice is the phase known as ice Ih, which is the most abundant of the varying solid phases on the Earth's surface. It can appear transparent or opaque bluish-white color, depending on the presence of impurities or air inclusions. The addition of other materials such as soil may further alter the appearance. The most common phase transition to ice occurs when liquid WATER is cooled below 0°C at standard atmospheric pressure. It can also deposit from vapour with no intervening liquid phase, such as in the formation of frost. Ice appears in nature in forms of snowflakes, hail, icicles, glaciers, pack ice, and entire polar ice caps. It is an important component of the global climate, and plays an important role in the WATER cycle.
