Investigating the Rock Cycle (Searchlight Books: What Are Earth's Cycles?)

"Solid introductions to natural cycles pack lots of information into clear, straightforward presentations. Plant Life Cycles includes flowering, cone-bearing, and seedless plant cycles, while Rock Cycle explains the formation and relationship of sedimentary, metamorphic, and igneous rocks. Water Cycle covers topics such as condensation, evaporation, and precipitation, while Carbon Cycle examines carbon bonds, photosynthesis, and climate change. Each title provides suggestions for simple experiments and observations, clearly identifying activities requiring adult help. Text boxes placed next to photos and diagrams pose relevant questions and offer additional facts. Because each book deals with a different topic, librarians can choose volumes as needed to supplement or update collections in specific subject areas. VERDICT: These basic overviews serve as good resources for independent investigators or report writers."--School Library Journal, Series Made Simple

Igneous rocks, sedimentary rocks, and metamorphic rocks make up the three main types of rocks. But did you know that rocks are constantly being created, destroyed, and created again? Or that rocks are changed by weather, erosion, heat, and pressure? See the rock cycle in action in this fascinating book.
