Learning Objectives

Each statement represents an important learning objective that relates to one or more sections of this lab. After you complete this exercise you should be able to:

*Distinguish between relative and numerical dates.

*List and explain the principles used to determine the relative ages of geologic events.

*Apply appropriate relative dating principles to determine a sequence of geologic events.

*Describe several different types of fossilization.

*Explain how fossils are used to date rocks and correlate rock layers.

*Explain the principle of radiometric dating, including half-life, parent isotope, and daughter product.

*Determine numerical dates for sedimentary strata.

*List the sequence of major events that have occurred on Earth and compare the span of geologic time to the length of human history.
