Weather

"In this well-designed `photo-book,' Simon takes a careful look at the weather--what it is, what causes it, and what affects it. Simple, direct explanations of the atmosphere, cold and warm fronts, and the formation of snow and hail are beautifully complemented by full- and half-page color photographs and diagrams....Solid, useful, and accessible, this is a very valuable 40 pages."--Booklist.
