Absolute dating methods determine how much time has passed since rocks formed by measuring the radioactive decay of isotopes or the effects of radiation on the crystal structure of minerals. Paleomagnetism measures the ancient orientation of the Earths magnetic field to help determine the age of rocks.

What is an example of an absolute dating technique?

Absolute dating techniques include radiocarbon dating of wood or bones, potassium-argon dating, and trapped-charge dating methods such as thermoluminescence dating of glazed ceramics.

What is your absolute age?

Absolute age is the numeric age of a layer of rocks or fossils. Absolute age can be determined by using radiometric dating. The age of the fossil will be an age range between the ages of the two volcanic layers.
