The main techniques used in absolute dating are carbon dating, annual cycle method, trapped electron method, and the atomic clocks.
Each element is made up of atoms, and within each atom is a central particle called a nucleus.
Within the nucleus, we find neutrons and protons; but for now, let's just focus on the neutrons.
Radiometric dating is another crucial technique through which the exact age can be obtained.
In radiometric dating, the radioactive minerals within the rocks are used to know about the age of the object or the sites.
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.
