Book Description: Phenomena of the sky, including rainbows, meteors, tornadoes and the northern lights, are examined and explained in this look at the natural world. The book is an inquiry into the dozens of the world's most interesting and baffling phenomena: what causes rainbows and mirages; what are the mechanics behind such spectacular events as tornadoes, hurricanes and thunderstorms; why do birds and insects migrate, and how do they navigate over hundreds of miles to do it; and how did previous civilizations explain windstorms, eclipses and the bizarre but, well-documented cases of fish, reptiles, snails and even snakes that have rained to earth? Author Jerry Dennis and illustrator Glenn Wolff approach these baffling questions with curiosity and wonder, and even suggest ways to observe firsthand the extraodinary occurrences that take place in the skies. Arranged by seasons, these essays blend scientific findings with historical anecdotes, personal observations, and lore and superstition.
