Water..

Water is one of the secrets of life, and a fundamental source of all life without which it cannot exist. Earth is the richest known planet in terms of water. Water has a controlled, balanced cycle during which water transforms into most of its forms, such as vapor, condenses into water droplets, hail, or ice, and melts into liquid water. Its density changes, so the water cycle between Earth and the atmosphere is not the only cycle. Water also has intertwined cycles in a tightly controlled system to create a biological and abiotic environmental balance necessary for the life of Earth and its inhabitants.
