<P> Water is the transparent , tasteless , odorless , and nearly colorless chemical substance that is the main constituent of Earth 's streams , lakes , and oceans , and the fluids of most living organisms , and that is vital for all known forms of life , even though it provides no calories or organic nutrients . Its chemical formula is H O , meaning that each of its molecules contains one oxygen and two hydrogen atoms connected by covalent bonds . Water is the name of the liquid state of H O at standard ambient temperature and pressure . It forms precipitation in the form of rain and aerosols in the form of fog . Clouds are formed from suspended droplets of water and ice , its solid state . When finely divided , crystalline ice may precipitate in the form of snow . The gaseous state of water is steam or water vapor . Water moves continually through the water cycle of evaporation , transpiration ( evapotranspiration ) , condensation , precipitation , and runoff , usually reaching the sea . </P>
