What scientific method does Richards use to determine the age of biological specimens?

  • Radiocarbon Dating

  • Chemical Reactions

  • Microbe Analysis

  • Astrophysics

Answer

Radiocarbon dating is a scientific technique used to determine the age of organic materials by measuring the amount of the radioactive carbon isotope, carbon-14, present in the sample. The method, pioneered by Willard Libby, is based on the principle that all living things absorb carbon-14 from the atmosphere, and when they die, the carbon-14 decays at a predictable rate.
