The student should discuss various radiometric dating systems, including radiocarbon dating,
uranium-lead, rubidium-strontium, samarium-neodymium, and potassium-argon. Especially
important is recognition that different half-lives for these systems allow them to date a
variety of events in the geologic record. Fission-track and tree-ring dating should also be
discussed. The student should also discuss effects of metamorphism on radiometric dating and analytical uncertainties in chemical analyses.
