water

Water is the most abundant resource on our planet. It comes in three forms: liquid state (liquid), solid state (ice), and gaseous state (water vapor or steam). Though most of the water on earth is in our oceans, polar icecaps and glaciers, lakes, rivers, aquifers, and clouds are all sources of water on our planet. (http://en.wikipedia.org/wiki/Water)

Water is also an essential ingredient for life on earth. All life forms on our planet require water to survive. The majority of water on earth is not fresh water. Though not all life on earth requires fresh water, human and other life does require it to survive. Through evapotranspiration water is carried overland and distributed to most the plant live that requires unsalted water. This water also fills the freshwater lakes, rivers, aquifers and ponds that are supply the water for the freshwater users. (http://en.wikipedia.org/wiki/Water)

The chemical structure of water is what makes it unique. Water is attracted to it’s self, and bonds to it’s self through polar bonds. Hydrogen atoms are negatively charge, oxygen atoms are positively charged. The difference on these charges are what causes water to bunch together. If it wasn’t for gravity, a drop of water would make a perfect sphere. (http://ga.water.usgs.gov/edu/waterproperties.html)

Water is known as the universal solvent. This makes it important to life because it dissolves more substances than anything else on earth. This allows water to dissolve and move the essential nutrients of life, and move them through our bodies and the bodies of the other living organisms on earth.
