Earth is different from any other planet or moon in the Solar System: it is the only one with liquid water on its surface. In fact, more than 70 percent of the earth's surface is covered by oceans. In clear, concise text and more than 20 breathtaking full-color photographs, a noted science writer explores our enormous ocean world.
