Relative Dating vs. Absolute Dating: What's The Difference? 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. 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. 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.

Absolute dating is the process of determining an age on a specified chronology in archaeology and geology. Some scientists prefer the terms chronometric or calendar dating , as use of the word "absolute" implies an unwarranted certainty of accuracy. In archaeology, absolute dating is usually based on the physical, chemical, and life properties of the materials of artifacts, buildings, or other items that have been modified by humans and by historical associations with materials with known dates such as coins and historical records. For example, coins found in excavations may have their production date written on them, or there may be written records describing the coin and when it was used, allowing the site to be associated with a particular calendar year.

Dating Rocks and Fossils Using Geologic Methods

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. 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.
