← ScienceWhich mechanism permits isotopic dating of archeological samples?
A)Constant radioactive decay rate✓
B)Variable isotopic formation rates
C)Stable chemical reaction kinetics
D)Consistent cosmic ray bombardment
💡 Explanation
Isotopic dating relies on the constant radioactive decay rate of specific isotopes as a form of radiometric dating; because the decay rate is constant and known, the age can be determined through measuring isotope ratios rather than alternative environmental variables.
