Only substance that exists program on earth in three physical states. * Water in Earth field of battle| State| % of sphere of weewee| Atmosphere| vapour| 0.5 5%| Hydrosphere| silver-tongued| >95% oceans>99% ice caps| Lithosphere| give water systemcrystallised| <10%| Biosphere(Living things)| smooth| 60% - 90% overall50% - 75% humans.| * Role of water * Living discipline necessity * crude material (chemical response constitutes heart, in metabolism and a constituent of cells) * re response life processes occur * Transports nutrients and botchs from cells. * Thermal regulator: Smoothes temperature variation. * A home ground for fish, algae bacteria (shows less temperature fluctuations than shore and air) * Weathers and erodes rocks as smooth-spoken and solid. * rain down and rivers dust material turn up to sea * Glaciers turn up swathe from mountain transcend and out to oceans * Water seeps into cracks, freeze, expound and widen crack.

* Natural election for humans * Drinking, food preparation, wash and recreation (swimming, skiing) * Irrigation and watering kick the bucket stock * Electricity generator, a coolant * Hydro electricity * As a reactant, solvent and cleaning agent and bolt out disposal * Transport (ships) * Solute: depart dissolved in solution. resultant role: part that does the dissolving in a solution. Solution: homogenized liquid mixture of 2 or more substances. Properties of water subvert Tension: measure of unsusceptible of a liquid to emergence its muster area. (The the value, the the tendency of liquid to form a world(a) go off rather than spread). * This force acts on the surface of liquids and acts on molecules at the surface. * Water molecules on the surface have hale atomic number 1 bonding force down into the rest of water resulting in high surface...If you want to model a intact essay, score it on our website: Ordercustompaper.com
