Earth in Change, the: The Earth's Crust

Tells the story of the changing land features of our planet. Ways in which ice, wind, and water act to wear away the surface of the earth, and how sedimentation, the action of volcanoes and earthquakes, and other forces help to build it up, are carefully described and illustrated. Scenes of Glacier National Park, Vesuvius, and Paricutin volcanoes and other rich geologic sources throughout the world contribute to a real understanding of the dynamic processes that change the surface of the earth.
