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.

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.
