Water supply from nature ice

The ice is a solid phase, usually crystalline, of a non-metallic substance that is liquid or gas at room temperature .





The-ice normally from-water, technically restricted to one of the 15 known crystalline phases of-water in non-scientific contexts, which is known to be the most abundant of these phases. It can appear transparent or an opaque bluish white color, depending on the presence of impurities such as air. The addition of other materials such as soil may further alter the appearance.









The most common phase transition to solid phase occurs when liquid phase is cooled below 0 °C (273.15 K, 32 °F) at standard atmospheric pressure.








The-ice appears in nature in forms as varied as snowflakes and hail, icicles, glaciers, pack-ice.
