Rosen / PowerKids Pr . 2013. lib. ed. $22.60; ebk. $22.60. Gr 3-5 Each volume of 20 related questions and answers provides a basic overview of an earth-science topic. Because every section is brief, browsers or reluctant readers who tackle a page or two might be encouraged to explore further. The question-and-answer exchanges are accompanied by small illustrations with informative captions relating to the main texts. Diagrams, such as one of the electromagnetic spectrum or one of ocean ridges and rifts, are more visually engaging than many of the photos. Although each volume stands alone, the following pairs would work well together because the topics are closely related: Water Cycle and Earth's Oceans, Rocks and Plate Tectonics, Earth's Atmosphere and Weather and Climate .
