The liquid that is made up of two parts hydrogen and one part oxygen is water. Water takes up over seventy percent of the earth’s surface. Your body is made of about sixty percent water.

Water can be a noun: it is the colorless, odorless liquid that all living things need to survive. Water can be a verb: as in watering the plants, getting teary, or urinating. When people talk about freezing and boiling, they are usually talking about the temperatures at which water freezes (32˚ F) and boils (212˚ F). Humans use water to bathe, cook, make fountains in the backyard, and mix with lemon juice and sugar to make lemonade.
