Perfect for budding geologists ages 6-9, this colorful reference book delves into more than 100 different types of rocks, minerals, gemstones, crystals, and fossils, explaining what each one is, how it's formed, and how it's been utilized throughout history. My Book of Rocks and Minerals is bursting with amazing stats, handy identification tips, and historical facts about what can be found below the Earth's surface. Photographic features introduce different geological categories, covering everything from the deepest caves to the farthest reaches of outer space, while high-resolution images offer a closer look at unusual phenomena found underground, like glow-in-the-dark rocks and beautiful gemstones. After they're finished reading, kids can take their fascination one step further by using the catalog and activity pages provided in the back of the book to help them collect and group rocks, and, in the process, discover how different rock types fit into the world around them.
