| Water
is a molecule that consists of two hydrogen atoms and one oxygen atom.
When these atoms are heated to a high temperature, they join to form
water. The scientific way to write this molecule is "H2O."
Since most of the water on earth was created when the earth was forming,
the water you are drinking today may have been a drink for a dinosaur
or maybe a part of Cleopatra's bath water! |

Water
occurs naturally in three forms
that people see every day.

as humidity in the air.
-
