Radiometric dating takes advantage of the fact that the composition of certain minerals (rocks, fossils and other highly durable objects) changes over time. Specifically, the relative amounts of their constituentelementsshift in a mathematically predictable way thanks to a phenomenon calledradioactive de...
The law of large numbers works so well, that the main source of error in carbon dating comes not from the randomness of the decay of carbon-14, but from the rate at which it is produced. The vast majority is created by bombarding...
Radiometric dating is classified as an absolute dating technique rather than a relative dating technique. Absolute dating using scientific processes to determine an exact age or an age within a tight range. Relative dating uses the position of rock in a set of strata to determine its age based ...
Radiocarbon datingworks by comparing the three different isotopes of carbon. Isotopes of a particular element have the same number of protons in their nucleus, but different numbers of neutrons. ... Most14C is produced in the upper atmosphere where neutrons, which are produced by cosmic rays, re...

More than 70 meteorites that have fallen to Earth have had their ages calculated by radiometric dating. The oldest of these are between 4.4 billion and 4.5 billion years old. Fifty thousand years ago, a rock hurled down from space to formMeteor Craterin Arizona. Shards of that asteroid have...
Scientists can estimate when a cave painting was made using radiometric dating, either using the rate of decay of the isotope carbon-14 in the pigments, or the rate of uranium decay in the surrounding rocks. Some paintings in Europe are thought to date back as far back as the Upper Paleoli...
Our knowledge of the actual ages rests on radiometric dating, now over a century old. This method is particularly applicable to igneous rocks, especially basalt intrusions and radioactive ash, which occur interspersed throughout sediments worldwide. The book gives an excellent account...
