Biology definition for relative dating
Correlation techniques are locally useful and depend on recognition of an event whose age is known, such as a volcanic eruption or a paleomagnetic reversal.Geologic studies of active tectonism are greatly aided by definition and time calibration of local stratigraphic sequences.
This is a method that does not find the age in years but is an effective technique to compare the ages of two or more artifacts, rocks or even sites.
It implies that relative dating cannot say conclusively about the true age of an artifact.
It is possible to tell the number of years ago a particular rock or archeological site had been formed.
Two broad categories of classification methods are relative dating and absolute dating.
Dating is a technique used in archeology to ascertain the age of artifacts, fossils and other items considered to be valuable by archeologists.
