Final answer:
The law of superposition helps determine relative dates, not absolute dates, which require techniques like radiometric dating.
Step-by-step explanation:
By applying the law of superposition, relative dates can be determined. This geological principle helps scientists establish the sequence in which layers of sediment were deposited, but it does not provide numerical ages. For absolute dating, techniques such as the measurement of radioactive isotopes are used to determine the numerical age of rocks, minerals, and fossils, which is essential for establishing an item's age in years.
The law of superposition can be used to determine relative dates, which are the order of events in time. It does not provide absolute (numerical) dates. Therefore, the answer is D. relative.
