What is a carbon dating

Answers

GPT-4o mini
Carbon dating, also known as radiocarbon dating, is a scientific method used to determine the age of an organic material by measuring the amount of carbon-14 it contains. Carbon-14 is a radioactive isotope of carbon that is formed in the atmosphere when cosmic rays interact with nitrogen. Living organisms absorb carbon, including carbon-14, from the environment during their lifetime. When an organism dies, it stops taking in carbon-14, and the isotope begins to decay at a known rate, with a half-life of about 5,730 years.

By measuring the remaining levels of carbon-14 in a sample and comparing it to the expected levels of carbon-14 in the atmosphere, scientists can estimate how long it has been since the organism died, typically up to about 50,000 years. Carbon dating is widely used in archaeology, geology, and other fields to date ancient organic materials, such as bone, wood, and artifacts.
