Explain relative dating
Then after another 5,000 years half of the remaining parent isotope will have decayed.
While people are most familiar with carbon dating, carbon dating is rarely applicable to fossils.
Relative age allows scientists to know whether something is older or younger than something else, while absolute age means that scientists know the exact number in years that have passed since the object was created.
Relative age will require the comparison of two or more objects, whereas absolute age does not.
Absolute dating is used to determine a precise age of a rock or fossil through radiometric dating methods.That is, scientists cannot tell exactly how old the layers are in years to the present date, only which is older than the other.
