These artifacts can be placed in order, but requires external information to determine which end of the series is younger or older.Absolute dating determines the age of artifacts in terms of the number of years before the present, with reference to a fixed time scale.So if our methods of radiometric dating are correct, then we would predict that rocks dated to the same age would have the same polarity, which they do.If this does not completely prove that radiometric dating is correct, it does at least show that (barring a wildly improbable coincidence) there is at least a one-to-one relationship between the dates produced by radiometric methods and the true dates, and so it must be taken as an argument in favor of these methods.QUESTION: What is the difference between relative and absolute dating techniques?

Cross dating involves comparing similar artifacts from similar sites that may be of similar age.But it is equally far-fetched to imagine that three different mechanisms interfered with the three processes in such a way as to leave the dates concordant; that would require either a preposterous coincidence, or for natural processes to be actually conspiring to deceive us: an idea which is, if anything, even more preposterous. But in this case there is a perfectly reasonable and straightforward explanation for why the dates are concordant, namely that they are correct.Similar remarks may be made about the agreement between radiometric dating of rocks, sclerochronology, and dating by rhythmites.According to the laws of superposition, a strategic layer that is higher has been deposited more recently.

The oldest strata are at the bottom of the sequence.Is it plausible that we have damaged their very different internal mechanisms in such a way that they are all running fast or slow but still in perfect synchrony?
