Earth Cycles

More than an earth cycle, and more than
a rock cycle, these books show readers the intricate layers of cycles within cycles. With Q&A features and a chapter on how pollution corrupts natural cycles, and with clear diagrams that illustrate the flow of life and energy, this series is the most comprehensive available on this science. It serves as a valuable supplement to the news about volcanoes, pollution in the environment, and earthquakes that appears weekly in newspapers.
