The world's oceans cover more than 70 percent of Earth's surface. But how much do children really know about our planet's main bodies of water? Oceans of the World gives readers the basics on the world's five main oceans, through beautiful photos and simple text. Colorful maps, fact-filled sidebars and captions, a table of contents, a phonetic glossary, sources for further research, an index, and an introduction to the author all aid in comprehension.
