Describes the causes and consequences of landslides, avalanches, and other, sometimes rapid, sometimes slow, downward movements of rocks, soil, and/or snow. Goodwin opens the book with a description of a landslide he witnessed as a child. Through the use of good analogies, the well-organized text goes on to compare landslides, slumps, creep, and avalanches, and then concisely explains the mechanism responsible for each. |
