How do scientists determine the age of fossils ?

Sagot :

The majority of the time, experts agree that radiocarbon dating is the most popular technique. A radioactive carbon isotope with a distinct number of neutrons, carbon-14, is measured as part of this approach. In the environment, carbon-14 is commonplace.

By analyzing the ratio of two distinct isotopes in a sample, radiometric dating can be used to establish the age of rocks. Geologists can establish the age of a material using tools like this thermal ionization mass spectrometer because radioactive isotopes decompose in a predictable amount of time. Experts in dating rocks and fossils are known as geochronologists. Using radiocarbon dating, they can frequently age fossils that are less than 50,000 years old. Dates for numerous intriguing events have been determined using this technique.
