Carbon Dating
My nerdy brother wants to start a radioactive dating website! The use of radiometric, or radioactive, dating was initiated in 1907 by Bertram Boltwood.
Radioactive dating techniques, such as radiocarbon dating or uranium-lead dating, provide an absolute age for rocks by measuring the decay of radioactive isotopes within them. This helps determine the actual age of rocks rather than their relative age.
Radioactive dating estimate the age of rocks.
Carbon-14 is an example of radioactive dating.
Radioactive dating refers to the process of measuring the age of an object using the amount of a given radioactive material it contains. Relative dating, meanwhile, measures the order of past events, without determining their absolute age.
By far the most common is radioactive dating which involves checking the amount of a given radioactive isotope in a given sample is left over (and calculating from the half-life [the time it takes for a radioactive element/isotope to decay to half the original amount]). Another one would likely be tree-ring dating which only determines the age of trees by how many rings it has.
The carbon isotope used in radioactive dating of artifacts is carbon-14. It is produced in the atmosphere by cosmic ray bombardment and is absorbed by living organisms. When an organism dies, the amount of carbon-14 decreases over time through radioactive decay, which can be used to determine the age of the artifact.
Carbon dating
Radioactive dating helps geologists determine the age of rocks and minerals by measuring the amount of radioactive isotopes present and their decay products. This information can be used to establish the age of Earth, study the history of geomorphic processes, and analyze the timing of geological events.
Radioactive dating can be used to estimate the absolute age of an object.
