Detailed explanation-1: -Radiocarbon dating involves determining the age of an ancient fossil or specimen by measuring its carbon-14 content. Carbon-14, or radiocarbon, is a naturally occurring radioactive isotope that forms when cosmic rays in the upper atmosphere strike nitrogen molecules, which then oxidize to become carbon dioxide.
Detailed explanation-2: -The carbon-14 method was developed by the American physicist Willard F. Libby about 1946. It has proved to be a versatile technique of dating fossils and archaeological specimens from 500 to 50, 000 years old.
Detailed explanation-3: -Carbon dating is used to determine the age of fossils.
Detailed explanation-4: -Absolute dating uses radiometric dating methods to determine the age of a fossil (or a rock). Essentially, this method uses the radioactive minerals found in fossils and surrounding rocks. Interestingly, these radioactive minerals almost act like a geological clock, providing a clear-cut age of a fossil.
