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. Absolute dating provides a numerical age or range in contrast with relative dating which places events in order without any measure of the age...
Radiometric dating, radioactive dating or radioisotope dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.
The techniques scientist need for absolute dating did not become available until the later half of the 20th century. Absolute dating uses clues, such as the emperor's face on a coin, to date an artifact. Tree ring dating offers over 1,000 years of clues in dates of artifacts from the American Southwest.

Absolute Dating Absolute dating can be achieved through the use of historical records and through the analysis of biological and geological patterns resulting from annual climatic variations, such as tree rings (dendrochronology) and varve analysis.
Relative vs Absolute Dating Dating is a technique used in archeology to ascertain the age of artifacts, fossils and other items considered to be valuable by archeologists. There are many methods employed by these scientists, interested in the old, to get to know the age of items. It is possible to tell the number of […]

Dating techniques are procedures used by scientists to determine the age of an object or a series of events. The two main types of dating methods are relative and absolute. Relative dating methods are used to determine only if one sample is older or younger than another.

Geologists often need to know the age of material that they find. They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years. This is different to relative dating, which only puts geological events in time order.
