1. You are an archaeologist studying prehistoric human populations in Peru. You want to determine the age of a carbonized corn cob from a site you excavated, which you hypothesize to be 3,000 yBP. Which chronometric method would be appropriate for testing your hypothesis

Radiocarbon dating (or carbon-14 dating). This is a type of chronometric techniques used to determine the age of an organic material by using radioactive isotopes of carbon. It is used by archaeologists and environmental scientists. Radiocarbon dating can span dates from a few hundred years ago right back to approximately 50 000 years ago.

Explanation:

Chronometric dating also called absolute dating is an archaeological dating technique used to give results in calendar years before present time. Chronometric techniques include:

Radiometric dating Radiocarbon dating Dendrochronology Fluorine testing Pollen analysis Thermoluminescence
