Water Facts
Water is a clear liquid that is found on earth, and is the most important natural resource on the planet because all forms of life rely on it in some form for survival, either directly or indirectly. Water is made up oxygen and hydrogen elements and its chemical name is H2O. Water can be found in liquid form, or when it is in its frozen state it is called ice. When in its gas state water is called either water vapour or steam. Approximately 70% of the surface of the earth is covered in water. Earth is not the only planet to have water. Scientists have discovered that water is found on Mars in its solid form - as polar ice caps.
