Description: Correlated with "Heath Elementary science" textbooks. Uses animation to show the ways in which minerals have been deposited in the earth. Reviews the forces acting upon the earth's crust and the resulting changes; shows how minerals are concentrated as a consequence of these changes by being deposited in veins, by washing into stream beds and low areas, and by seeping through the earth in solution. Describes how oil was trapped in the earth's folds and how coal was formed.
