It has an unusually high boiling point and freezing point. Water allows us to live in an environment of fluctuating temperature changes, while keeping our bodies a steady 98.6 degrees. Water is a universal solvent. Water is also chemically inert. Without affecting the makeup of the substances it carries, water enables food, medicines and minerals to be absorbed and used by the body.
Water has a unique surface tension.
Water in plants can therefore flow upward against gravity, bringing life-giving water and nutrients to the top of even the tallest trees. Water freezes from the top down and floats, so fish can live in the winter. Ninety-seven percent of the Earth's water is in the oceans. But on our Earth, there is a system designed which removes salt from the water and then distributes that water throughout the globe. Evaporation takes the ocean waters, leaving the salt, and forms clouds which are easily moved by the wind to disperse water over the land, for vegetation, animals and people.
