Part 1: Write a discussion, 300 words minimum, that describes how scientists "date" rocks. By that, I mean discuss the methods by which we determine a rock's relative and absolute ages. Be sure to summarize all the principles of relative dating we went over (e.g., cross-cutting relationships). Also, please discuss how absolute dating works. (Focus on Isotopic Dating, also called Isotope Geochronology). explain what isotopes are and how we measure them to determine the age of a sample.
