Gr 4–8—Nearly every page of this visual guide supplies striking and large format photos of rocks with multi-sentence captions. As illuminated in the pictures, rocks can be grouped by many attributes, such as colors, locations, physical appearances, textures, and striations. Young readers can learn more by examining text interwoven between the many visual examples of rocks. Famous natural wonders and examples of fossilization worldwide are showcased. This comprehensive series makes clear that rocks are constantly changing over time, because they are impacted by environmental factors, such as erosion, heat, melting, and pressure, as well as human activities. Nonfiction features, such as a table of contents, glossary, index, and a website from the publisher, complete the set.
