If the archaeologist finds a sample suitable for carbon dating, then an absolute date may be assigned to an object.Similarly for paleontologists who find layers of fossils.Tools like radiometric dating allow some samples to be assigned a certain age to within some accuracy.
What is the difference between radioactive and radioactivity?
Carbon dating is also used to search for evidence of cosmic ray activity, which may provide a sense of past astronomical events and potentially reveal a pattern.
Short Answer: Both relative dating and absolute dating are tools used to give temporal characteristics to a sequence of events.
Both are attempting to get information on the history of events.
This can also occur in nature, but it is unusual for it to happen.
Natural Radioactivity is a spontaneous process of disintegration.
The primary difference is that absolute dating assigns an actual time or age to an event or object.
Relative dating simply says one is older than the other but no age is specified.
Taking K-Ar as an example, the sample must be selected from a rock believed to be representative of the geological process being investigated. This can also occur in nature, but it is unusual for it to happen.
