Earth in Change: The Earth's Crust

Complete catalog record
The changing land features of our planet, the ways in which ice and 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 rich, geologic sources throughout the world contribute to an understanding of the dynamic processes that change the surface of the earth.
