Unit 6 - Earth's Geologic History
Reading Assignment: Chapter 11 - Geologic Time
Learning Objectives
After reading, studying, and discussing the chapter, students should be able to:
11.1 Explain the principle of uniformitarianism and discuss how it differs from catastrophism.
11.2 Distinguish between numerical dates and relative dates and apply relative dating principles to determine a time sequence of geologic events.
11.3 Define fossil and discuss the conditions that favor the preservation of organisms as fossils. List and describe various fossil types.
11.4 Explain how rocks of similar age that are in different places can be matched up.
11.5 Discuss three types of radioactive decay and explain how radioactive isotopes are used to determine numerical dates.
11.6 Distinguish among the four basic time units that make up the geologic time scale and explain why the time scale is considered to be a dynamic tool.
11.7 Explain how reliable numerical dates are determined for layers of sedimentary rock.
