What type of rock is most suited for radiometric dating? -

As we learned in the previous lesson, index fossils and superposition are effective methods of determining the relative age of objects. In other words, you can use superposition to tell you that one rock layer is older than another. But determining the absolute age of a substance its age in years is a much greater challenge. To accomplish this, scientists use a variety of evidence, from tree rings to the amounts of radioactive materials in a rock. In regions outside the tropics, trees grow more quickly during the warm summer months than during the cooler winter. This pattern of growth results in alternating bands of light-colored, low density "early wood" and dark, high density "late wood".

What type of rock is most suited for radiometric dating

The farther down the fossil is the older it gets. There are two main methods for dating fossils. The first is relative dating which examines the layers of rock around the fossil to find an approximate date. The other is absolute dating, which measure the decay of carbon atoms. Archaeologists dont date fossils they date artifacts now to stop correcting you

Index fossils are fossils of organisms that only existed during a relatively short period of time and were found globally widespread. Since the organism was widespread and was only around for a short time, if we know when it was around, we then know how old a rock is that contains it. Index fossils can be used to help determine the relative age of rock layers.
