Different forms of water
Water exists in many forms including dew, liquid, snow and ice. Salty oceans contain more than 97% of all water on earth, oceans play an important role in diluting and degrading pollutants that may flow into them. Polar ice caps are the next largest component of earth's water surface, they have a large influence on the worlds climate and provide essential habitat to unique forms of life. The rest of freshwater on earth is what we see everyday.
