Water

Water is the most common liquid on Earth but also the most important. It is almost everywhere on Earth - in the air and the clouds; in oceans, lakes, rivers, and ice; in plants and animals; and beneath the Earth's surface. But water cannot be taken for granted. A person can survive for nearly a month without food but only several days without water. If there were no water, there would be no life.

With clear, simple text and stunning full-color photographs, award-winning science writer Seymour Simon shows in his new book how essential water is to our very existence and to our planet.
