Rocky cliffs at the seashore often reveal the geological processes at work creating rocks and minerals. This fascinating book helps explain: - how erosion, sediment deposit, and underground pressure create rocks and minerals - fossils and dazzling gemstones - how the Grand Canyon was created - how metals are made from ore - what space rocks teach us
I teach 4th grade and have looked high and long for a book that 9yr. olds could use to study the Rock Cycle. This book had wonderful illustratons labelled with clarity. The text was clear and easy to understand. The photos gave great examples of various groupings of rocks. My co-teachers and I all bought more copies of this great rock book for our students to use.Excellent!
