Earth's Oceans (Where's the Water?)

Many people know that about 70 percent of Earths surface is covered by water. But they may not know that the oceans hold nearly 97 percent of the water on Earth. From the Arctic to the Pacific, these huge bodies of water are important to the health of our planet. Readers learn the different boundaries and characteristics of each of Earths oceans, complemented by full-color photographs both above and below the surface. The main content and fun fact boxes include both the water cycle and geographic information and emphasize other science and social studies curriculum topics, such as conservation.
