Definition relative dating method dating for nonsmokers
The advantage of this technique over the conventional radiocarbon method is that it requires a far smaller sample size and can potentially provide dates going back to around 100,000 B. At present, however, AMS dates generally are for events less than organic molecules that are building blocks of proteins.
There are at least 20 different kinds of amino acids in living things.
Using relative dating the fossil is compared to something for which an age is already known.
For example if you have a fossil trilobite and it was found in the Wheeler Formation.
Relative age dating also means paying attention to crosscutting relationships.
Relative time can not determine the actual year a material was deposited or how long deposition lasted; it simply tell us which events came first.
This means that a quartz sandstone deposited 500 million years ago will look very similar to a quartz sandstone deposited 50 years ago.
