Document Summary
Pile up a lot of sediment as a result create weight so it will sink down. Why water is really weird but vital to earth system. Vast amounts of it on earth and makes up oceans and life. Only substance occurring naturally in 3 states solid,liquid,gas: highest surface tension of all common liquids, dissolves more substances than any other solvent, unusual thermal properties are hugly imp for weather and climate system, ice floats. Are strong need a lot of energy to break them. Water have a bend polar which makes the weird properties. All substances have bonds between the molecules: van der waal"s forces. Cause molecules to be more strongly attracted to each other. Strong hydrogen bonds in water cause water to have high cohesion and surface tension. Polar molecule stick to other polar compounds such as substances w/ ionic bonds. Causes reduction in attraction between ions so they separate dissolve. Why ocean salty: water transporter of material.
