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.
Most commonly, the ancient factors of the rocks or objects are examined using the method called stratigraphy. In other words, we can say that the age in the relative dating is ascertained by witnessing the layers of deposition or the rocks.
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 the relative dating as many organisms have there remain in the sedimentary rocks.

This evaluation of the rocks and fossils in the 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. To evaluate the exact age, both the chemical and physical properties of the object are looked keenly. The main techniques used in absolute dating are carbon dating, annual cycle method, trapped electron method, and the atomic clocks.
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 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.
The radiometric dating is another crucial technique through which the exact age can be obtained. The four techniques used in absolute dating are radiometric dating, amino acid dating, dendrochronology, and thermoluminescence.
How are relative dating and absolute dating alike
Relative dating is the technique used to determine the age by comparing the historical remaining to the nearby layers. It is a less advanced technique when compared to absolute dating.

Some methods used in relative dating are stratigraphy, biostratigraphy, and cross dating. The absolute dating refers to a technique used to determine the exact age of the artefact or a site using methods such as carbon dating while relative dating refers to a technique used to determine which object or item is older in comparison to the other one.

Absolute dating determines the numerical age while relative dating arranges the fossils in an order. The precision in absolute ageing is high while the precision of the relative ageing is low. Absolute age is a quantitative measurement while relative age is a qualitative measurement.
