IMPORTANCE OF WATER TO LIFE 2IntroductionWater is found everywhere is nature and it is a necessity component to almost every organic reaction that takes place in the universe. It is the most copious component on the surface of the earth. Majority of the water on the earth’s surface is found in the sea and the rest is found in solidstate as ice and the rest exists in gaseous state. All life on the earth’s surface require the product so that is can be able to survive. Other than being the main supporter of life on the planet earth it also has an effect on the nonliving things such as erosion and the weathering process or rocks. Water acts as a sink to heat that is it is able to absorb excess heat and buffer the temperatures within the earth’s atmosphere preventing extreme weather changes. Water is the most vital part inthe entire living complex system straight from the habitats down to the unit of life that is cell.The chemical and physical properties of waterWater covers over 70% of the total earth’s atmosphere which implies that it supports a lot of life. Water is made up of two elements that is two atoms of hydrogen and one atom of oxygen(Woodward, 2009). The three element are bond using covalent bonds. Because the valence electrons of water are shared unequally between the two hydrogen atoms and the oxygen atom it makes it more polar. The unequal sharing of the electrons leaves the hydrogen atoms more positive whereas the oxygen atoms remain negative. The polarity of water makes it adhesive to many substances making it an excellent solvent. Water is described as a universal solvent because it simple terms it dissolves very fast than any other liquid substance. Some substances such as table salt is able to dissolve very fast. Common salt also called sodium chloride is positively charged therefore the sodium ions bind with the negatively charged oxygen ion whereas the negatively charged chloride ion binds with the

The process of ion bondingis very important because it makes it possible for nutrients to be transported in living organisms both plants and animals. When water is flowing from the sky into the earth it dissolves gases which when it reaches the seas it supports the life of the living creatures.
