The boiling and freezing points of water are affected by solutes, as well as air pressure, which is in turn affected by altitude. When finely divided, crystalline ice may precipitate in the form of snow. Liquid water has weak absorption bands at wavelengths of around 750 nm which cause it to appear to have a blue colour. The water molecule is composed of two hydrogen atoms, each linked by a single chemical bond to an oxygen atom. Water occurs as a liquid on the surface of Earth under normal conditions, which makes it invaluable for transportation, for recreation, and as a habitat for a myriad of plants and animals. Water collaborates with the International Conference on Flood Management (ICFM) and Stockholm International Water Institute (SIWI) . [68] The length of time water remains in storage is highly variable: some aquifers consist of water stored over thousands of years but lake volumes may fluctuate on a seasonal basis, decreasing during dry periods and increasing during wet ones. When an oxygen atom forms a single chemical bond, it shares one of its own electrons with the nucleus of another atom and receives in return a share of an electron from that atom.
