This attractive introduction. . .takes advantage of the book’s horizontal trim to provide fine, color photos of thunderstorms as well as diagrams depicting the formation of lightning and the time difference between sight of lightning and the sound of its thunder. Photos and related design elements take up two-thirds of each double-page spread, leaving plenty of white space surrounding the two to four brief lines of large-print text. The writing concentrates on the facts more than the audience. . . . Teachers will appreciate the book’s short text and large illustrations. From The Weather series, this volume is well suited for sharing with groups.
