    Learning Outcomes

    After completing this chapter, you should be able to:

    • Apply basic geological principles to determine the relative ages of rocks.
    • Understand the importance and significance of unconformities.
    • Use isotopic data to estimate the numeric (absolute) age of a rock.
    • Explain why an understanding of geological time is critical to both geologists and the public in general.
