Question

if a scientist wanted to determine the absolute age of a fossil found in layer b, which of the following should they use? radiometric dating relative dating law of original horizontality law of superposition

Explanation:

Radiometric dating is used to determine the absolute age of a fossil by measuring the decay of radioactive isotopes. Relative dating only gives the order of rock layers. The law of original horizontality and the law of superposition are principles for relative - dating and determining the sequence of rock layers, not for absolute age determination.

Answer:

Radiometric dating
