Detailed explanation-1: -Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon.
Detailed explanation-2: -The ratio of stable carbon to carbon-14 is then used to calculate the date when the radioactive decay process started; in other words, the time when the plant or animal died. This means that by using radiocarbon dating, we can tell when someone in the past hunted an animal or cut down a tree at an archaeological site.
Detailed explanation-3: -Dating games When the plant or animal dies, they stop absorbing, but the radioactive carbon that they’ve accumulated continues to decay. Measuring the amount left over gives an estimate as to how long something has been dead.
