Some people spend their whole lives keeping an eye on the “sleeping giant” hovering over their land. Some volcanoes erupt with regularity, flinging molten rock high in the air or oozing a steady stream down the mountain side. Others, like Mount St. Helen in Oregon, slumber for more than a century before erupting. There are a lot of interesting tidbits of information tucked into this brief overview of volcanic activity and many of the photos are spectacular. Plus, who would not want to make her/his own volcano? The reader will learn about the four types of volcanoes, the type of rock they make, and myths.
