Vedclass · Answer

(C) The age of rocks is determined using radioactive dating techniques. Specifically,the decay of radioactive isotopes like $U^{238}$ into stable isotopes like lead $(Pb^{206})$ is measured. By calculating the ratio of the remaining radioactive parent isotope (uranium) to the accumulated stable daughter isotope (lead),scientists can accurately estimate the absolute age of the rock. Therefore,both the amount of uranium and the amount of lead are critical factors in this calculation.

The age of a rock is calculated on the basis of:
