The most effective way for a scientist to find the actual, numerical age of a rock is:
**d. Measure the amounts of radioactive elements remaining in the rock.**
This method, known as radiometric dating, allows scientists to determine the age of the rock by measuring the decay of radioactive isotopes within it.
