Difference between absolute and relative dating of rocks
For example, fission track dating measures the microscopic marks left in crystals by subatomic particles from decaying isotopes.Another example is luminescence dating, which measures the energy from radioactive decay that is trapped inside nearby crystals.
The atoms of some chemical elements have different forms, called isotopes.
These break down over time in a process scientists call radioactive decay.
The four methods involved in absolute dating are radiometric dating, amino acid dating, dendrochronology, and thermoluminescence while biostratigraphy, stratigraphy, and cross dating are involved in the relative dating.
The precision in absolute ageing is high while the precision of the relative ageing is low.
The absolute dating refers to a technique used to determine the exact age of the artefact or a site using methods such as carbon dating while relative dating refers to a technique used to determine which object or item is older in comparison to the other one.
