Foldables Geological Time Make the following Foldable to help you identify the major events in each era of geologic time.
Foldables Fold the top of a vertical piece of paper down and the bottom up to divide the paper into thirds.
Foldables Turn the paper horizontally; unfold and label the three columns as shown.
Foldables Read for Main Ideas As you read the chapter, list at least three major events that occurred in each era. Keep the events in chronological order. For each event, note the period in which it took place.

Reviewing Main Ideas 1 Life and Geologic Time • Geologic time is divided into eons, eras, periods, and epochs. • Divisions within the geologic time scale are based largely on major evolutionary changes in organisms. • Plate movements affect organic evolution.
Reviewing Main Ideas 2 Early Earth History • Cyanobacteria evolved during Precambrian time. Trilobites, fish, and corals were abundant during the Paleozoic Era. • Plants and animals began to move onto land during the middle of the Paleozoic Era.
Reviewing Main Ideas 2 Early Earth History • The Paleozoic Era was a time of mountain building. The Appalachian Mountains formed when several islands and finally Africa collided with North America. • At the end of the Paleozoic Era, many marine invertebrates became extinct.
Reviewing Main Ideas 3 Middle and Recent Earth History • Reptiles and gymnosperms were dominant land life-forms in the Mesozoic Era. Mammals and angiosperms began to dominate the land in the Cenozoic Era. • Pangaea broke apart during the Mesozoic Era. Many mountain ranges formed during the Cenozoic Era.
