GEOLOGY

Explore geology through the pages of a book.

This interactive presentation invites the reader to “touch, pound, scrape, or press” the pages just as a geologist might do to examine rocks. Tapping, blowing, jumping up and down, and rubbing hands together are just some of the actions called for. From time to time, the imagined actions mimic the geologic process: tracing and retracing the route of a river to create a canyon, or pressing a hand into clay to create a fossil. Schaefer’s exploration follows a clear narrative arc, beginning and ending with our familiar Earth. She moves smoothly from topic to topic, describing Earth’s layers, offering examples of the three major types of rocks, and discussing the uses of rocks and the metals we extract from them. This leads to the building of rockets to explore other rocks in space. Returning to Earth, readers are asked to notice the rocks, minerals, and metals all around—and even inside their bodies. Finally, an activity guide leads readers to discover that rocks vary in hardness. The relatively simple text is arranged on a plain white background, with Santiago’s clear digital illustrations supporting the information. The few humans pictured have dark hair and skin. The appealing, accessible design adds to the value of this simple introduction.
