Feel the warmth of a summer day; look at falling snow; listen to distant thunder. Weather is all around us, always changing all the time. Dazzling photos enhance this clear introduction to the many faces of this powerful force of nature."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.
