Seventy percent of Earth is covered in water, and most of that water is ocean. From the vibrant reefs along ocean shores to the cold, dark depths of the midnight zone, Earth's oceans are home to a diverse wealth of plant and animal life. Featuring eye-popping illustrations, fact-filled text, and easy-to-read diagrams, this book explores the ocean's myriad habitats and the environmental and human factors that impact them. Readers will be interested to discover that many of the items that they use on a daily basis come from the ocean.
