Reseña de Horn Book
Large pages contain detailed cross-sections that examine geological processes such as plate tectonics, oceans, mountains, and volcanoes. Though the book contains some color photographs, illustrations are often used where a photograph would be more effective. However, the in-depth explanations are accurate and are augmented by map inlays that place each topic within a geographic framework. Ind. From HORN BOOK 1994, (c) Copyright 2010.

Reseña de Booklist
Gr. 4-7. This very oversize volume looks at the geography of the earth, including the earth's crust, the ocean floor, and various kinds of rocks as well as the history of the earth. Photographs are less in evidence here than in some of the publisher's other books, but the color illustrations of such things as cutaways of earth features and examples of natural structures are mostly big and bold, surrounded by text and smaller pictures. When photos are used, for instance to catalog the various kinds of rocks, they are very effective. Not the only book you'll want to have on the subject, but a useful one.
