continental drift

Explains how mountains are created and how the surface of the earth changes.

Describes the theory of plate tectonics and the various forces that continue to change the surface of the earth. Discusses the history of the theory as well as evidence that seems to dispute it.

Recounts Alfred Wegener's attempts to prove his theory that the world's continents had once formed a solid landmass before splitting apart and floating to their current positions, describing how his theory was rejected by the scientific community and his expeditions to Greenland in search of evidence that would prove his theory.

Presents an introduction to continental drift and plate tectonics, in simple text with illustrations, including information on the structure of the earth, the theory of plate tectonics, and the hazards caused by plate movements.
