It uses fossils to help pinpoint the ages of rocks.

help me its wotrth 60 give me thr right awnser or i fail the grade

It uses fossils to help pinpoint the ages of rocks.

Explanation:

Radiocarbon  dating can not be used  to determine the age of rocks.

Carbon dating works well only for objects that are less than 50,000 years.  Most rocks are far older than that. Over time, carbon-14 decays gradually  into nitrogen. Hence, we can not really use radiocarbon dating to determine the absolute age of a rock sample since the carbon-14 in the fossils of ancient rock samples may have completely decayed.

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
