Vigil The outermost layer of the Earth is broken up into a dozen or more solid rock slabs (called tectonic plates) that are moving slowly relative to one another. These motions are illustrated by this artist's conception of a slice into the Earth from the wall map "This Dynamic Planet: World Map of Volcanoes, Earthquakes, Impact Craters, and Plate Tectonics" by the U.S. Geological Survey (USGS), the Smithsonian Institution, and the U.S. Naval Research Laboratory.

A 77-page USGS booklet ("This Dynamic Earth: The Story of Plate Tectonics") complements the wall map "This Dynamic Planet" and describes in non-technical language how earthquakes, volcanic eruptions, and energy and mineral resources relate to plate-tectonic processes.
