Children's LiteratureCracking Up is a picture book about how weather and water wear away rock and how this erosion becomes a recycling process. The story begins on a rocky ledge above the sea. The ledge has been there for hundreds of years, but wind, rain, ice, and sun, as well as birds nesting on the ledge, has worn away bits of the ledge. The strong waves beneath the cliff have also caused the base of the cliff to break into pieces. Bit by bit, erosion is taking place. The erosion process continues when pieces of the cliff ledge topple into the sea and sink to the bottom of the ocean. The rocks are tossed around and become smaller. Gradually, the lighter pebbles are carried toward the bay and closer to the beach. Eventually they make their way to the beach where they are so small they are the size of grains of rice. The pebbles have turned into sand. At the end of this process, people visit the beach and enjoy the grains of sand beneath their feet. The colorful illustrations help to tell the story of erosion. Step-by-step the process is visualized in a clear and entertaining manner. Back cover material includes more information on erosion, science experiments, and a glossary. This is a good introductory book to learning about soil erosion. 2006, Picture Window Books/Capstone Press, Ages 7 to 10.
