In the field of Geology, dating is an important term as it is a technique through which evaluation regarding the age and period about the fossil, remains, the archaeologists do valuables and artifacts.
At first, there were not many methods of dating were available, but now with advancement in the technology, we mainly have two types of the techniques to ascertain ages of ancient belongings.
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.
Relative Dating and Absolute Dating are two types of such techniques which are under practice to determine the age of the fossils, objects or civilizations.
The relative dating is the technique in the Geology through which the age is determined with relation to the other objects.
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.
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, the absolute dating is the technique, using which the exact age of the artifacts, fossils, or sites are ascertained.
This rate of decay is constant for a given isotope, and the time it takes for one-half of a particular isotope to decay is its radioactive half-life.
For example, about 1.5 percent of a quantity of Uranium 238 will decay to lead every 100 million years.
This evaluation of the rocks and fossils in the relative dating is known as the biostratigraphy.
