Budding petrologists will uncover a wealth of information about rocks lying between the pages of the slim book. One in a series by Bridgestone Science Library titled "Exploring the Earth," the book offers readers chapters where they will discover what a rock is, different types of rocks and the Mohs scale of hardness. Full-page color photographs add depth and dimension to the large print-text. A vivid, color illustration accompanies the story of the rock cycle from magma found deep in the earth through the many changes that transform the rock from one stage to the next. Fun-facts can be found throughout the text and a sidebar explains how scientists use light and form to study their rock specimens. A hands-on activity allows readers to see for themselves how rocks form. Endnotes include a glossary, Internet sites, resource books and other useful addresses for those who want to learn more. This volume is a very useful resource for home and elementary classrooms. 2002, Capstone Press, $18.60. Ages 4 to 8. Reviewer: Sue Reichard

Gr 2-4-Two serviceable introductions to popular topics. Olien touches on the types of fossils, some famous finds, and fossil fuels. Richardson outlines the three types of rocks, how they are formed, the rock cycle, and Mohs scale of hardness. Each book contains full-color photographs and a hands-on experiment. David Lambert's Rocks and Minerals (Watts, 1986; o.p.) and Joanna Cole's The Magic School Bus inside the Earth (Scholastic, 1987) are similar in scope.-Sandra Welzenbach, Villarreal Elementary School, San Antonio, TX Copyright 2001 Cahners Business Information.
