Example include carbon14-nitrogen, uranium-led, uranium-thorium. Relative dating instead allows for identifying the sequential order of geological events one relative to the other.This is based on the concept that, in a normal depositionary sequence, the deepest layers are also the oldest.In radiometric dating, the radioactive minerals within the rocks are used to know about the age of the object or the sites.Absolute dating(also known as radiometric dating) is based by the measurement of the content of specific radioactive isotopes of which the "half time" is known.The absolute dating is more reliable than the relative dating, which merely puts the different events in the time order and explains one using the other.Radiometric dating is another crucial technique through which the exact age can be obtained.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.

The main techniques used in absolute dating are carbon dating, annual cycle method, trapped electron method, and the atomic clocks.

Half time is the time needed for half of a given quantity of an isotope to decay in its byproducts.

Comparing the quantity of the parent form and the byproduct will give a numerical value for the age of the material containing such isotopes.

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

Contrary to this, absolute dating is the technique, using which the exact age of the artifacts, fossils, or sites are ascertained.
