2. Explain how geologic time is recorded in rock layers.
3. Identify the major time intervals that the geologic time scale represents.
4. Identify two types of environmental changes that cause mass extinctions.
5. A mass extinction event occurs when there is an significant decrease in the number of species in a relatively short period of time. Which of the following conditions has been the most frequent cause of mass extinction events?
6. Explain how the number of animal species has both increased and decreased during Earth’s history.
7. Identify two unique traits that may have helped mammals survive the mass extinction at the end of the Mesozoic era.
Answers
Section 1
1. Uniformitarianism assumes that geologic change is slow. Catastrophic assumes that geologic change is fast. Paleontology is a science that uses fossils to study past life.
2. Uniformitarianism is assumed that geologic change happens slower that
