These techniques can be grouped as numerical, relative dating, and correlation.The example used here contrasts sharply with the way conventional scientific dating methods are characterized by some critics (for example, refer to discussion in "Common Creationist Criticisms of Mainstream Dating Methods" in the Age of the Earth FAQ and Isochron Dating FAQ).After the song and video were posted on You Tube, it went unnoticed for a month or two but then exploded, a pop culture supernova, soaring to tens of millions of views within a week or two as the world stood in judgment and more or less declared “Friday” the worst song of all time, and also asked who does this Rebecca Black think she and think she won’t face our scorn and derision?
To determine the relative age of different rocks, geologists start with the assumption that unless something has happened, in a sequence of sedimentary rock layers, the newer rock layers will be on top of older ones.
This rule is common sense, but it serves as a powerful reference point.
Tradition paleontological and biostratigraphic correlation methods are still perhaps the most common relative dating methods used by geologists.
More modern correlation technologies include use of marine stable isotope records, paleomagnetic dating, tephrachronology, geomorphological methods, sedimentation characteristics, and other geochemical and radiometric methods.
Maybe you'd be pleasantly surprised, or even shocked, to know that he was talking about Diane Lane, who is 19 years his senior at 49 years old!
