The relative dating is less advanced technique as compared to the absolute dating.
In relative dating, mostly the common sense principles are applied, and it is told that which artifact or object is older than the other one.
To tell it simply, fossils and archaeological objects are supposed to have the same age as the sediment in which they are embedded.
And fossils and archaeological objects which come from a deeper stratigraphical layer are supposed to be older.
And not every fossil or archaeological object can be dated, since radiometric dating methods are mostly rather costly, and the financial means of most research teams are limited.
But one must be careful by interpreting the results of excavations since stratigraphical layers may present abnormalities.
Likewise, fossils and archaeological objects which come from a more superficial stratigraphical layer are supposed to be younger.
Between the years of 17, James Hutton and William Smith advanced the concept of relative dating.
These techniques are more complex and advanced regarding technology as compared to the techniques in practice in the relative dating.
The absolute dating is also sometimes referred as the relative numerical dating as it comes with the exact age of the object.
The relative dating is the technique to ascertain the age of the artifacts, rocks or even sites while comparing one from the other.
In relative dating the exact age of the object is not known; the only thing which made clear using this is that which of the two artifacts is older.
