Explains volcanic activity, how it originates in the earth's core, and what happens when a volcano erupts. Surveys monitoring devices, documented eruptions, and the ecological effects.
"Gr. 4-8. The first two volumes in the Natural Disasters series focus on natural disasters and their impact on humans and the environment.Hurricane, typhoon, and cyclone are all regional terms used to describe a tropical revolving storm. A brief introduction to the power and destruction of such storms is followed by discussions of wind patterns, how storms develop, and their impact on humans and the environment. Because of their resemblance to hurricanes, tornadoes are given cursory treatment. Efforts to predict and track tropical storms, precautions to take, and theories about global warming as a factor in storm precipitation are also briefly addressed.Volcanoes describes the power, unpredictability, and impact of volcanic activity and takes a look at some historically well-known volcanoes and recent eruptions, including Mount St. Helens. The immediate and long-range impact of volcanic activity is explored as is the difficulty of predicting eruptions.The oversize volumes use color photographs and drawings extensively. Each double-page spread addresses one topic, with clear, well-labeled, and well-matched photographs accompanying the discussion. These books are better written and more informative than Goodman's Natural Wonders and Disasters in the Planet Earth series [BKL D 1 91], for the same age group. Their large size, appealing subject matter, clear explanations, and manageable text make them good choices for individual or classroom use. Each volume includes a glossary; a fact file, loaded with statistics, is also appended to each, but the format is unattractive and somewhat confusing. There is no documentation. ~--Karen Hutt"
