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.Though using similar methods, these two techniques differ in certain ways that will be discussed in this article.

But, how can we determine how old a rock formation is, if it hasn’t previously been dated?One argument in favor of the absolute dating methods presented in the preceding articles is that they should work in principle.If they don't, then it's not just a question of geologists being wrong about geology, but of physicists being wrong about physics and chemists being wrong about chemistry; if the geologists are wrong, entire laws of nature will have to be rewritten.Scientists can use certain types of fossils referred to as index fossils to assist in relative dating via correlation.Index fossils are fossils that are known to only occur within a very specific age range.
