Question: Why do we need to calibrate radiocarbon dates?

Calibration of radiocarbon results is needed to account for changes in the atmospheric concentration of carbon-14 over time. These changes were brought about by several factors including, but not limited to, fluctuations in the earths geomagnetic moment, fossil fuel burning, and nuclear testing.

Is carbon-14 dating relative or absolute?

Radiocarbon dating One of the most widely used and well-known absolute dating techniques is carbon-14 (or radiocarbon) dating, which is used to date organic remains. This is a radiometric technique, since it is based on radioactive decay.

Which object would a geologist date using carbon-14 dating quizlet?

Useful only for dating organic material from once living organisms. (Bones, wood, parchment, and charcoal) uses isotopes of carbon-14 to determine the age of once-living organisms.
