They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years.

As the word relative tells that defining the object with respect to the other object, it will be pertinent to mention here that actual numerical dates of the rocks or sites are not known in this type of dating.

Other than rocks, fossils are the other most important elements in relative dating as many organisms have there remain in the sedimentary rocks.

These use radioactive minerals in rocks as geological clocks.

The atoms of some chemical elements have different forms, called isotopes.

This evaluation of the rocks and fossils in relative dating is known as the biostratigraphy.

The absolute dating is the technique to ascertain the exact numerical age of the artifacts, rocks or even sites, with using the methods like carbon dating and other.

These techniques are more complex and advanced regarding technology as compared to the techniques in practice in relative dating.

The absolute dating is also sometimes referred to as the relative numerical dating as it comes with the exact age of the object.

These break down over time in a process scientists call radioactive decay.

Each original isotope, called the parent, gradually decays to form a new isotope, called the daughter.

In other words, we can say that in relative dating the archaeologist determines that which of the two fossil or the artifacts are older.
