The Story of the Earth presents the complex history of the Earth from its formation through to the emergence of man and his influence on the planet. Peter Cattermole and Patrick Moore trace the evolution of Earth from its beginnings in the primeval Solar Nebula, through its bombardment by cosmic particles, continental drifting and the formation of mountains and oceans, and end with a study of the last Ice Age and the rise of man. While the approach is roughly chronological, time is spent in explaining some of the methods that geologists, physicists, chemists and biologists use to discover what processes have contributed to the internal make-up and external appearance of our unique planet. Accounts are included of the dramatic events that are still changing the face of the Earth: volcanoes and photographs - several taken from orbiting satelites - help to elucidate the story.

Assumptions and speculation about the Spanish conquerors'' treatment of the indigenous miners at Potosí, Peru, have long obscured the complexity of the motives in mining there. Peter Bakewell''s innovative study incorporates the Indians'' viewpoints, finding that they were willing to work for the Spaniards. Many of them quickly combined their technical skills and individual initiative to become the first silver mining entrepreneurs of Potosí. Although Indian entrepreneurship declined after the 1750s, a substantial portion of the native work force retained more control over its condition of labor and life than previously recognized. -- From publisher''s description.
