Part 1: Write a discussion, 300 words minimum, that describes how scientists "date" rocks. By that, 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, 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.
