Water (chemical formula: H 2 O ) is a transparent fluid which forms the world's streams, lakes, oceans and rain, and is the major constituent of the fluids of organisms. As a chemical compound , a water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds . Water is a liquid at standard ambient temperature and pressure , but it often co-exists on Earth with its solid state, ice ; and gaseous state, steam ( water vapor ). It also exists as snow , fog , dew and cloud .
Water covers 71% of the Earth's surface. It is vital for all known forms of life . On Earth, 96.5% of the planet's crust water is found in seas and oceans, 1.7% in groundwater, 1.7% in glaciers and the ice caps of Antarctica and Greenland, a small fraction in other large water bodies, and 0.001% in the air as vapor , clouds (formed of ice and liquid water suspended in air), and precipitation . Only 2.5% of this water is freshwater , and 98.8% of that water is in ice (excepting ice in clouds) and groundwater
Water vapor , water vapour or aqueous vapor , is the gaseous phase of water . It is one state of water within the hydrosphere . Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice . Unlike other forms of water, water vapor is invisible. Under typical atmospheric conditions, water vapor is continuously generated by evaporation and removed by condensation . It is lighter than air and triggers convection currents that can lead to clouds.
