Question by : How does radiometric dating help scientists pinpoint the age of a fossil?
A) Radiometric dating allows scientists to find fossils in only the lowest and oldest layers of sediment.
B) Radiometric dating shows the rate of decay of radioactive material present in any object. Scientists can use that data to find the absolute age of the fossil.
C) In radiometric dating, scientists mix the carbon in a fossil with carbon from similar fossils whose age they know. By comparing the carbon they can tell the exact age of the fossil.
D) In radiometric dating, scientists place samples of a fossil in certain liquids until the samples dissolve. The rate at which they dissolve indicates the age of the fossil.
