# When was absolute dating first used

Like tail fins on a Cadillac, artifact styles and characteristics change over time, coming into fashion, then fading in popularity. The standard graphical result of seriation is a series of "battleship curves," which are horizontal bars representing percentages plotted on a vertical axis.Plotting several curves can allow the archaeologist to develop a relative chronology for an entire site or group of sites.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.The basis for stratigraphy seems quite intuitive today, but its applications were no less than earth-shattering to archaeological theory.For example, JJA Worsaae used this law to prove the Three Age System.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 relative dating the exact age of the object is not known; the only thing which made clear using this is that which of the two artifacts is older.

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.

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 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.
