Product Description
How do minerals collect in ancient bones? Why are fish fossils sometimes found on land? How can some feathers be preserved for millions of years? This series explores the causes and effects that shape our world. From the underwater volcanoes that sprout into islands, to the rushing waterfalls that spark electric currents, this series demonstrates how both natural and man-made phenomena occur.
