Grade 3–6—This hi/lo title describes the layers of the earth; active, dormant, and dead volcanoes; the different volcanic structures that can be found (strato- and shield volcanoes, and cinder cones), and their effects on the environment. What volcanologists do and the potential dangers they face are addressed as well. The book is broken down into easy-to-read chapter spreads, and color photographs and illustrations contribute to the text. However, the "Heads up on Expert Reading" insets are potentially patronizing to the intended audience.—Farida S.
