Ascientist has a fossil that was found in a layer of rock close to earth’s surface. he believes that the fossil is around 12,000 years old. which method would best allow the scientist to confirm the actual age of the fossil? a. finding another fossil in a deeper layer of rock b. finding another fossil in the same layer of rock c. using carbon/nitrogen absolute dating d. using potassium/argon absolute dating

When it comes to determining the age of fossils there is absolute and relative dating. Relative dating is used to determine which fossil is older, while absolute dating is used when determining the age of a particular fossil. Rocks that contain radioactive elements in it, allow scientists to determine the age of fossils using the amount of radioactivity. Carbon-nitrogen absolute dating is a method for determining the age of fossils using radioactive isotopes of these elements.

The answer is: C.

can you give a picture of the map, i'll be able to update my answer!
