Water H2O dihydrogen monoxide. A colourless, tasteless liquid with some very peculiar properties that stem from the bent H-O-H structure of its molecules. Water is distinguished from other common terrestrial substances in existing in all three phases at atmospheric temperatures and pressures. The phase changes, are of great significance in many geophysical processes. The same is true of the large specific heat of liquid water and ice relative to both land surface and atmosphere. Water's complex absorption spectrum gives rise to the greenhouse effect.
