Question
Chapter 20, Problem 72AP
Interpretation Introduction
Interpretation:
The statement, “Thescientist is able to tell the age of the fossil,”is to be explained.
Concept introduction:
Radiometric dating is a technique used to date objects and rocks based on the decay rate of the various radioactive isotopes.
Carbon-14 dating is a type of analysis in which the objective age of carbon-based material is determined.
To determine the age of an object, the half-life of a radioactive isotope is used as an atomic clock.
A mass spectrometer determines the type and amount of isotopes present in the rock.
