WebGeologists use both relative and numerical dating techniques to determine the ages of rocks, fossils, or geologic features. Numerical dating techniques provide a specific age for each rock or fossil, whereas relative dating techniques don't give specific dates but rather indicate which rocks are older or younger than others. WebJan 14, 2014 · Geologists use radioactive dating to... - determine the relative age of rock layers. - tell the difference between molds and casts. - tell where one soil horizon begins and the next one ends. - determine the absolute ages of rocks. I think it is to determine the absolute ages of rocks, but I'm not quite sure.
