While in the absolute dating, isotopes of carbon are used for dating fossils. The absolute dating is more precise than relative dating because it tells the exact age of the fossils. Both are ultimately based on the fossils found in the strata.

Which is more accurate relative or radiometric dating?

Actually none. radiometric dating can not easily be used to date fossils and when the dates between the radioactive dates contradict the relative dates based on fossils the fossils always win.

How does absolute dating differ from relative dating?

What is the difference between relative and absolute age? Relative age is the age of a rock layer (or the fossils it contains) compared to other layers. It can be determined by looking at the position of rock layers. Absolute age is the numeric age of a layer of rocks or fossils.
