question 24
radiometric dating is possible because the rates of decay of radioactive isotopes
○ change over time
○ change from place to place
○ are constant
○ vary widely

Explanation:

Radiometric dating relies on the constant decay rates of radioactive isotopes, which are unaffected by time or location. This constancy allows scientists to calculate the age of materials by measuring the ratio of parent to daughter isotopes.

Answer:

are constant
