Everything young readers 12 and up ever wanted to know about these unique formations. A sinkhole is a hole in the ground, but a very special one, appearing anywhere where rock dissolves allowing the ground above it to sink. Some sinkholes happen gradually, but others open up almost instantly. (These are the ones you hear about in the news when one swallows a house.) Sinkholes happen worldwide—from valleys in the high Himalayan Mountains to the depths of the Adriatic Sea, from the crystal-clear springs of Florida to the oases of the Arabian Desert. With 140 color photos, this book illustrates how sinkholes are an important part of our natural environment. Climbing through caverns, sliding into sinkholes, and clambering up volcanoes is all in a day's work for Sandra Friend, who regularly ventures out into the field while researching articles and books. She has written more than 150 articles on travel, outdoors, and geological topics, and is the author of a series of five children's earth science educational books, Exploring Planet Earth. Sinkholes completes more than five years of research on a subject that has fascinated her since the 1970s. An Orlando resident, Friend can frequently be found hiking and backpacking Florida's many scenic trails.
