Differences between relative chronometric dating techniques
Proteins are composed of different combinations of amino acids assembled in chain-like molecules.
Amino acids are primarily composed of carbon, oxygen, hydrogen, and nitrogen.
This is useful in geology because you can age layers of rock relative to other layers.
Just like we know that dinner comes after lunch even though we may not know what time it occurs.
So instead of human records, geologists use techniques such as radiometric dating.
These processes involve sampling rocks and determining how old they are from their rate of decay.
Since absolute time gives us points of reference, it helps calibrate relative time, also called chronostratic time ('strata' means 'layers').
Here, we are looking at events relative to other events.
