How can using radiocarbon dating to determine the age of fossils underground help determine the ages of the rock layers?
A. By determining the age of the fossil in the rock layer, you know the age of the rock fossil was found in and can then estimate the ages of the adjacent rock layers to it
B. By using radiocarbon dating, you can determine the amount of carbon still present in the rock, thus can use the equations of carbonation from chemical weathering to determine how long the rock was exposed to carbon dioxide
C. By determining the age of the fossil in the rock, you can estimate the material composition of the rock layer around it, since all rocks are formed a specific times in the past
