Before radiometric dating it was difficult to determine the actual age of an object. The relative dating is the technique to ascertain the age of the artifacts, rocks or even sites while comparing one from the other. Fossils are the key to determine the relative dating in sedimentary rocks. Watch the following video.

One we have it, all the processes that happened after the payment and before the solo become apparent. The circumstances of the object may allow one to say that one object is older than another without being able to assign a particular age to the objects. Long Answer: Sciences such as geology, paleontology and archeology are very interested in identifying the age of elements found and these scientists sometimes use either relative dating or absolute dating to characterize the age of the objects they study.

For example: If an archaeologist is studying past civilizations, the archaeologist may be able to say that in a particular location the ruins of once civilization were found to have been build on another and so the layers unearthed in an excavation convey the sequence of historical occupations without revealing the actual dates. Fossils are the key to determine the relative dating in sedimentary rocks. A layer that is higher is of later age than a layer that is absolute in order.

Difference between absolute dating and relative dating - Absolute age can be determined by using radiometric dating.

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 years ago a particular rock or archeological site had been formed. Two broad categories of classification methods are relative dating and absolute dating. Though using similar methods, these two techniques differ in certain ways that will be discussed in this article. As the name implies, relative dating can tell which of the two artifacts is older. This is a method that does not find the age in years but is an effective technique to compare the ages of two or more artifacts, rocks or even sites. It implies that relative dating cannot say conclusively about the true age of an artifact. Absolute dating, on the other hand is capable of telling the exact age of an item using carbon dating and many other techniques that were not there in earlier times. Relative dating makes use of the common sense principle that in a deposition of layers. A layer that is higher is of later age than a layer that is lower in order. This means that the oldest are the strata that are lying at the bottom. However, age of deposition does not mean the age of artifacts found in that layer. Artifacts found in a layer can be compared with other items found in layers of similar age and placed in order. However, archeologists still require further information to find out the items that are oldest and those that are youngest in the order. It is left for absolute dating to come up with the precise age of an artifact. This type of dating employs many dating techniques like atomic clocks, carbon dating, annual cycle methods, and trapped electron method. Dendrochronology is another of the popular method of finding the exact age through growth and patterns of thick and thin ring formation in fossil trees. It is clear then that absolute dating is based upon physical and chemical properties of artifacts that provide a clue regarding the true age. This is possible because properties of rock formations are closely associated with the age of the artifacts found trapped within them. The most popular method of radio dating is radio carbon dating which is possible because of the presence of C-14, an unstable isotope of carbon. C-14 has a half life of 5730 years which means that only half of the original amount is left in the fossil after 5730 years while half of the remaining amount is left after another 5730 years. This gives away the true age of the fossil that contains C-14 that starts decaying after the death of the human being or animal. In brief: Relative Dating vs. Upper most layers are considered the youngest while the lowermost deposition is considered as oldest.
