Baking and Crushing

The wide-format books in the Rock-ology series discuss facts related to geology. A typical double-page spread introduces a new topic in several short, large-print sentences supplemented by an info-circle carrying more information in smaller type. Separated on the page into individual sentences, the main text seems a bit disjointed even when the various parts are logically connected. The greater part of each spread is devoted to one or more captioned illustrations: photos, digital diagrams, and digital-collage pictures incorporating photographic elements. Though somewhat varied in quality, the colorful pictures are often effective. Each book includes a simple activity suitable for home or classroom use. Opening with the statue in the Lincoln Memorial, Baking and Crushing discusses the formation of metamorphic rocks as well as the quarrying of marble. Recommended as supplementary resources for larger collections.
