A sound basic introduction to the hows and whys of volcanoes, updated with colorful new graphics.

This update of the 1985 text includes accounts of a few historic eruptions (Mounts Vesuvius, Tambora, St. Helens, and Parícutin) and explains how and why volcanoes form. Plate tectonics as well as scientists' study of and efforts to predict eruptions are also covered. Instructions for an activity that involves making a baking soda and vinegar volcano are appended. The new illustrations excel at depicting ideas presented in the text.
