Which of the following is NOT true about relative dating? Question 4 options:

it uses radioactivity to get a more exact age of a fossil

it uses the nearby rock layers.

It finds the approximate age of fossils.

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.

i believe it is 40–40–20%

explanation:

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
