![]() ![]() Large quantities of water, ice, and steam are used for cooling and heating, in industry and homes. Much of the long-distance trade of commodities (such as oil, natural gas, and manufactured products) is transported by boats through seas, rivers, lakes, and canals. Fishing in salt and fresh water bodies is a major source of food for many parts of the world, providing 6.5% of global protein. Approximately 70% of the freshwater used by humans goes to agriculture. Water plays an important role in the world economy. Water moves continually through the water cycle of evaporation, transpiration ( evapotranspiration), condensation, precipitation, and runoff, usually reaching the sea. Small portions of water occur as groundwater (1.7%), in the glaciers and the ice caps of Antarctica and Greenland (1.7%), and in the air as vapor, clouds (consisting of ice and liquid water suspended in air), and precipitation (0.001%). Water covers about 71% of the Earth's surface, mostly in seas and oceans (about 96.5%). The gaseous state of water is steam or water vapor. ![]() When finely divided, crystalline ice may precipitate in the form of snow. Clouds consist of suspended droplets of water and ice, its solid state. It forms precipitation in the form of rain and aerosols in the form of fog. "Water" is also the name of the liquid state of H 2O at standard temperature and pressure.Ī number of natural states of water exist. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. Its chemical formula, H 2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. It is vital for all known forms of life, despite providing neither food, energy, nor organic micronutrients. Water (chemical formula H 2 O) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent ). The internationally recognized independent organization works to reduce the negative effects that unsafe products and processes have on our health and environment.Clouds in Earth's atmosphere condense from gaseous water vapor. Using a consensus based process, NSF creates standards, test and certifications for food and water industries.
