Catastrophic Events (Student Guide and Source Book)

What causes volcanoes in Hawaii? Why do earthquakes happen more often in California than in Virginia? Where do hurricanes and tornadoes form, and how are they different? You may have wondered about such questions. Natural catastrophic events are powerful and often dramatic forces. They can have a major effect on our planet Earth and on the living things on the planet. Each one appears to be an independent event. Yet the combination of these events over billions of years has helped to shape the earth as we know it. They will continue to change the earth in the future. This book explores questions like this along with other events.
