Geologists do not use carbon-based radiometric dating to determine the age of rocks. Carbon dating only works for objects that are younger than about 50,000 years, and most rocks of interest are older than that. Over time, carbon-14 decays radioactively and turns into nitrogen.

Is carbon-14 useful for establishing earths age Why or why not?

A Carbon-14 is not useful for establishing the age of Earth because its half-life is quite long in comparison to Earths age. B Carbon-14 is useful for establishing the age of Earth because its half-life is quite long in comparison to Earths age.

What would carbon 14 dating be primarily used to age?

Carbon-14 dating is a way of determining the age of certain archeological artifacts of a biological origin up to about 50,000 years old. It is used in dating things such as bone, cloth, wood and plant fibers that were created in the relatively recent past by human activities.

How can carbon-14 be used to determine the age of a fossil?

0:002:34Determining the Age of a Fossil Using Carbon-14 - YouTubeYouTubeStart of suggested clipEnd of suggested clipA fossil contains 60% of its original carbon-14 how old is the fossil. This is an example ofMoreA fossil contains 60% of its original carbon-14 how old is the fossil. This is an example of radioactive decay. So our equation is going to be a of T equals a naught e to the KT decay.
