We live on a water planet, and there is much for readers 9 to 12 to learn about it. This illustrated guide is a comprehensive exploration of our oceans, covering geography, ecosystems, and animals through a mix of illustrations, photographs, maps, and diagrams. Aspiring oceanographers can map out the oceans layers, from the sunlight zone to the abyss, exploring the conditions within each zone and the different creatures that live there, as well as exploring features of the ocean floor.
