Natural Wonders and Disasters

These first two volumes in the Planet Earth series feature dramatic, consistently crystalline color photos (some extending over two pages) and pithy chunks of text--both designed to increase children's understanding of, and appreciation for our planet. Goodman ( A Kid's Guide to How to Save the Planet ) gives brief accounts of such disasters as earthquakes, floods and cyclones as well as explanations of their geological causes. Wu relates his first-hand underwater experiences to introduce his book's sections on various marine habitats; he concludes with a somber look at future dangers to the oceans. Because of its narrower focus and personal touches, this volume is the more effective of the two, but both work well as introductions to the incredibly varied aspects of the world around us. Impressive additions to the ever-expanding roster of children's nonfiction. Ages 8-12. (Oct.)
