Document Summary
Water is essential for life, as we know it. Water is a liquid substance devoid of odor, taste and color, which exists in a more or less pure state in nature and covers a significant percentage (71%) of the surface of planet earth. Furthermore, it is a common substance in the solar system and the universe, although in the form of vapor (its gaseous form) or ice (its solid form). Water is essential for life as we know it, and the first forms of life in the world took place inside it. It has also occupied a central place in the imaginary of human civilizations, generally attributed to some deity or as the mythical deluge with which the gods devastate lost cultures. It was also considered one of the four elements of nature. This circuit is vital for the climatic and biological stability of the planet. Water is the universal solvent; most substances can be dissolved in it.
