- More than 500 million years ago, the seas covered much of what is now North America. Traces the development of the continent from a lifeless expanse of rock in pre-Cambrian times until the coming of man. By a skillful blending of animated maps, sequences showing natural processes and panoramic landscapes and museums dioramas, the building of the continent and the development of life are depicted. Also explores the vast natural resources of North America--precious metals and rare minerals, coal and oil and how they were formed.
- Topics: (Geology)
