29. scientists use various methods to determine the age of matter. which method below would a scientist most likely use to determine the age of a rock layer? a identify the oldest fossilized remains in the rock layer. b measure the magnetic strength of the material in a sample of the rock. c compare the composition of the rock sample with other rock samples of known age. d compare the amount of stable daughter elements present with the amount of radioactive parent element in the rock layer.

Answer

Brief Explanations:

Radiometric dating, which involves comparing the amount of stable daughter - elements to radioactive parent - elements, is a common and reliable method for determining the age of rock layers. Fossils can give relative ages but not as accurate as radiometric dating for rock layers. Measuring magnetic strength is more related to paleomagnetism and not the primary way to date rock layers. Comparing compositions with known - age rocks is less precise than radiometric dating for absolute age determination.

Answer:

D. Compare the amount of stable daughter elements present with the amount of radioactive parent element in the rock layer.
