The Science Behind Wonders of the Sun: Sun Dogs, Lunar Eclipses, and Green Flash

Gr 4–8—Providing scientific explanations for familiar and unusual natural phenomena, these books will intrigue most readers. Earth unravels the mysterious movement of boulders across Death Valley and considers the formation of caves, crystals, and erosional landforms. Water includes the dramatic account of an "exploding lake" in Cameroon and explains how scientists worked to mitigate the problem. Water, which contains the most maps and diagrams of the set, also introduces the ocean conveyor belt, iceberg formation, and tidal bores. Sun considers how solar ejections disrupt electronics on Earth and explains sunspot cycles, auroras, and sun dogs. The topics in Sky, such as comets and lightning, are the most standard, although the book expands on typical coverage. For example, cloud formations like asperitas and lenticular appear along with the more common cumulus. Appropriate photos accompany the explanatory texts.
