More substances can be dissolved by water than by any other material. The water molecule, with its magnet like opposite charges, is able to carry other substances suspended within itself, making it a nearly universal solvent. Water is able to climb of its own accord, a feat that results in capillary action in soils and in plants. Without this characteristic, water would not travel from the deepest root tip to the highest leaf. There would be no internal flow of nutrients in complicated organisms, and thus no complicated organisms. The trick occurs because the attraction of water molecules to themselves and to other molecules is so strong that they are drawn upward from one foreign molecule to another, always pulling along the adjacent water molecules. The climb is halted only by gravity. Great amounts of heat can be absorbed by water, making seas, rivers, lakes, and clouds vast energy storage banks. The release of stored heat from the ocean, for example, moderates climates, making coastal winters milder than those only a few miles inland.
