Water is a transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth’s streams, lakes, and oceans, and the fluids of most living organisms.

Water is vital for all known forms of life, even though it provides no calories or organic nutrients.

The chemical formula for water is H₂O, 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 H₂O 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, the solid state of water.

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, condensation, precipitation, and runoff, usually reaching the sea.
