This U.S.Geological Survey site shows how chemists and geologists use analytical chemistry to: determine the age of the Earth; show an extraterrestrial body collided with the Earth; predict volcanic eruptions; observe atmospheric change over millions of years; and document damage by acid rain and pollution of the Earth's surface.
