The law of superposition is based on the common sense argument that the bottom layer had to laid down first.

The bottom layer because it logically had to be laid down first must be older.

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.

Relative dating is a less advanced technique as compared to absolute dating.

Relative dating is used commonly when looking at the relative order of geological events.

What can complicate relative dating is when the strata is not the right way up!

We can absolute date materials but it will always have an uncertainty range, we can never know the age with infinite precision.

Relative dating is like looking at a multi-layered cake.

The relative dating is the technique to ascertain the age of the artifacts, rocks or even sites while comparing one from the other.An absolute age is one determined usually by mass-spectrometry where an isotope is measured and then an age can be calculated (a very very basic explanation).So in the end you can say this fossil is 50 thousand years old (always with an associated uncertainty).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.Most commonly, the ancient factors of the rocks or objects are examined using the method called stratigraphy.
