Book Description
Holly Keller has created vivacious new paintings for this favorite Reading Rainbow title about geology. Readers follow two enthusiastic rock hounds around the globe as they add to their collection. Along the way they will learn how sedimentary, metamorphic, and igneous rocks are formed. From the Egyptian pyramids to Roman roads, from the diamond ring on your finger to the pebbles under your feet, rocks are everywhere!
School Library Journal
More than just the title has been changed in this updated edition of Gans's Rock Collecting (Crowell, 1984). The topics are the samebasic rock formation; the characteristics of igneous, metamorphic, and sedimentary rocks; the uses of rocks in the past (Roman roads, Egyptian pyramids) and the present (cement); and, finally, a bit about rock collecting. The excellent diagrams, full-color photographs of specimens, and minor textual changes clarify the concepts (for example, Mohs' scale of hardness) and extend the presentation. Gans barely introduces collecting rocks in the field and organizing and storing them, but the pair of youngsters featured in Keller's brightly colored illustrations certainly convey the joys of being a rock hound.
