The Field Guide to Natural Phenomena [Wonders], subtitled The Secret World of Optical, Atmospheric and Celestial Phenomena (this book by Keith Heidorn and Ian Whitelaw seems to have two alternate main titles) describes and explains a range of natural phenomena that one is likely to meet. One might meet them while taking a long drive, for example. Included in the book are brief discussions of geysers, tides, clouds, mirages, meteors, waterspouts, rainbows, sundogs, aurorae, and much more.
This is a great little book, and well-illustrated. Families interested in teaching children about science might like to keep a copy in the family vehicle.
