Absolute age dates have confirmed the basic principles of relative time—for example, a uranium‐lead date from a dike that intrudes into an older rock always yields an absolute age date that is younger than the absolute age date of the enclosing rock.
Whats an example of absolute dating?
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.
