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. C) to systems such as uranium–lead dating that allow determination of absolute ages for some of the oldest rocks on Earth.

What do you think is the purpose of knowing the absolute and relative dating?

Geologists often need to know the age of material that they find. They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in numbers of years. This is different to relative dating, which only puts geological events in time order.
