evolution
superposition
erosion
uniformitarianism
- 3. Multiple Choice
Knowing the age of rocks important for understanding the history of Earth. One method for doing this is radioactive dating. This method allows geologists to _.
tell the difference between molds and casts.
tell where one soil horizon ends and the next one begins.
determine the absolute ages of rocks.
determine the relative ages of rock layers.
- 4. Multiple Choice
What are fossils?

footprints or burrows of small animals that live today
the preserved remains or traces of organisms that lived in the past
drawings of ancient animals or other organisms
- 5. Multiple Choice
What has the study of fossils allowed scientists to do?
study present ocean temperatures at different depths
analyze the chemical composition of sedimentary rocks and minerals
predict which organisms will become extinct in the future
describe past environments and the history of life
- 6. Multiple Choice
