It can be achieved through the use of historical records and through the analysis of biological and geological patterns. Although development of radiometric methods led to the first breakthroughs in establishing an absolute time scale, other absolute methods have limited applications. Chief among these are dendochronology, varve analysis, hydration dating, and TL dating.

In this article, we shall take a look back at the methods of absolute datingand see how we know that they can be relied on. 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.

But what is exactly a fossil and how is it formed? Have you ever wondered how science knows the age of a fossil? Read on to find out!

Absolute dating is the process of determining an age on a specified time scale in archaeology and geology. Some scientists prefer the terms chronometric or calendar dating, as use of the word "absolute" implies an unwarranted certainty and precision. Absolute dating provides a numerical age or range in contrast with relative dating which places events in order without any measure of the age between events. In archeology, absolute dating is usually based on the physical, chemical, and life properties of the materials of artifacts, buildings, or other items that have been modified by humans and by historical associations with materials with known dates.

Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks. Radioactive elements decay The universe is full of naturally occurring radioactive elements. Radioactive atoms are inherently unstable; over time, radioactive "parent atoms" decay into stable "daughter atoms.

Radiometric dating, often called radioactive dating, is a technique used to determine the age of materials such as rocks. It is 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 it can be used to date a wide range of natural and man-made materials.

It is an accurate way to date specific geologic events. This is an enormous branch of geochemistry called Geochronology. There are many radiometric clocks and when applied to appropriate materials, the dating can be very accurate.

Related to radiometric dating: Carbon 14 dating. A method for determining the age of an object based on the concentration of a particular radioactive isotope contained within it and the half-life of that isotope. Also called: radioactive dating. A method for determining the age of an object based on the concentration of a particular radioactive isotope contained within it.
