Let's rock!
Travel around the globe with our two adventurous rock hounds and learn how rocks form and change. Rocks are everywhere. Whether they are part of an anciant pyramid or under your very feet, they are always close by. Once you learn more about them, you won't be able to resist a collection of your own!
This book focuses on rocks and has a brief discussion of volcanoes, igneous rocks, crystals of the Moh's Scale of Hardness, sedimentary rocks, limestone, mountain building, metamorphic rock, and how to start a rock collection. |
