(4) YA Exploring Planet Earth series. These two volumes cover earth processes (primarily surface, though earthquakes are also included), describing wind and water erosion, avalanches, and landslides. The organization and text-heavy definitions are sometimes unclear, and detract from the otherwise informative presentations. Color photographs are helpful, though they cannot begin to cover the many references to natural phenomena found in the text. Bib., glos., ind.

(4) YA Exploring Planet Earth series. In a thorough, descriptive treatment of volcanology, Downs explains the basic taxonomy of volcanoes, eruptions, lava, and volcanic formations, providing many classic examples from around the world and throughout history. The six text-heavy chapters at times expand their discussion to include the chemistry and physics of eruptions. A good selection of color photos illustrates the variations in volcanoes and their products. Bib., glos., ind.

(4) 4-6 Exploring Planet Earth series. Downs provides detailed description of mineral identification, structure, formation, and uses by people through history. Even more factual information is included in boxes unnecessarily separated from the main text. The color photographs of minerals are helpful but few in number. The book also contains lists of websites and places to visit. Bib., glos., ind.
