(4) YA Extreme Earth series. In-depth descriptions of famous landforms frame sophisticated discussions of geologic history, processes, and theories. The case study format is detailed and informative, but the complex terminology and concepts may be difficult for all but the most advanced students to comprehend, particularly in Canyons. Each book's black-and-white illustrations don't do justice to the magnificent landforms but are supplemented by one eight-page color insert. Reading list, websites. Glos., ind. Review covers these Extreme Earth titles: Waterfalls, Canyons, Caves, and Lakes.
