Differences between relative chronometric dating techniques
It is a less advanced technique when compared to absolute dating.
Some methods used in relative dating are stratigraphy, biostratigraphy, and cross dating.
Since weather patterns tend to run in cycles of a number of years, the sequence of tree-rings in a region will also reflect the same cycling, as illustrated by the graph below.
By cross-linking core samples from living and dead trees, a master sequence of annual tree-ring widths can be compiled.

However, the longer bristlecone pine sequence is of little value except for cross-checking the reliability of other dating techniques because logs of this species are rarely found in association with ancient humans.A compass needle would have pointed to the south pole during some periods and to the north pole during others.Lava and volcanic ash deposits often contain the thermoremnant magnetic records of these reversals.The main difference between absolute and relative dating is that the absolute dating is a technique to determine the numerical age of a rock or a fossil whereas the relative dating is a technique that determines the relative age.Furthermore, absolute dating can be done with the use of radiometric dating while relative age is determined with respect to other layers.
