The science curriculum is full of processes that students need to understand and they can seem complicated when taken as a whole. This volume breaks down the rock cycle step by step, including brief explanations of the three kinds of rocks, erosion, and many key terms. Clear language and simple sentences present the information in an accessible way for readers of all levels. Complete with full-color photographs and a diagram showing the whole process, this book complements classroom learning and offers a great resource for readers in need of review.
