Archaeology radiometric dating
Based on a discipline of geology called stratigraphy, rock layers are used to decipher the sequence of historical geological events.
Relative techniques can determine the sequence of events but not the precise date of an event, making these methods unreliable.
Whereas, relative dating arranges them in the geological order of their formation.
The relative dating techniques are very effective when it comes to radioactive isotope or radiocarbon dating.
To find their age, two major geological dating methods are used.
Take a look at the diagram to understand their common functions.
When we observe the intersection in this diagram depicting these two dating techniques, we can conclude that they both have two things in common:1.
The rate of decay of these elements helps determine their age, and in turn the age of the rocks.
Amino acid dating: Physical structure of living beings depends on the protein content in their bodies.
