NounSingular radiometric dating Plural radiometric datings radiometric dating (plural radiometric datings)
From Wiktionary under the GNU Free Documentation License. Radiometric dating (often called radioactive dating) is a technique used to date materials, usually based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates. It is the principal source of information about the absolute age of rocks and other geological features, including the age of the Earth itself, and can be used to date a wide range of natural and man-made materials. Together with stratigraphic principles, radiometric dating methods are used in geochronology to establish the geological time scale. Among the best-known techniques are radiocarbon dating, potassium-argon dating and uranium-lead dating. By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change. Radiometric dating is also used to date archaeological materials, including ancient artifacts. Different methods of radiometric dating vary in the timescale over which they are accurate and the materials to which they can be applied. From Wikipedia under the
GNU Free Documentation License Is radiometric dating the only way to determine the age of the Earth? Q. And how accurate is it? Asked by Ramen Noodle - Mon Mar 22 16:50:37 2010 - - 2 Answers - 0 Comments A. It's not the only way but it's the most often used way to date the rocks and age of the earth. As far as being accurate, there are a number of evidences which contradict and falsify it. Radiometric dating is based on the "assumption" that decay rates have remained the same in the past 4,600,000,000 years as they have in the last 100 years of observations. However, scientists have observed dormant bacteria in fossils which are "presumably" dated to be tens of millions of years old...yet there is no known scientifically valid means or process for them to survive that long. Metabolic rates do not drop to zero even in dormancy. Other things like DNA, proteins, red blood cells, heme and soft tissues have been found in fossils...things which… [cont.] Answered by paul h - Mon Mar 22 17:22:55 2010 Is their a difference between absolute dating and radiometric dating or are they the same thing? Q. Is their a difference between absolute dating and radiometric dating or are they the same thing? Asked by Daulton S - Tue Feb 5 19:21:14 2008 - - 4 Answers - 0 Comments A. Absolute dating, refers to dating by a fundamental property of the rock itself, as opposed to relative dating, which categorizes a rock as older or younger than some other reference rock. Dating a rock at over 65 million years because it has a dinosaur fossil in it and we know that dinosaurs died out 65 million years ago is an example of relative dating. Radiometric dating on the other hand, which compares the isotopic ratios of various elements within the structure of the rock, is a form of absolute dating, as it deals with a property of the rock itself, without reference to any other material.
