Our planet inherits a large number of artifacts and monuments bestowed upon us by older historic civilizations.
These remains are subjected to dating techniques in order to predict their ages and trace their history.
This is different to relative dating, which only puts geological events in time Most absolute dates for rocks are obtained with radiometric methods.
These use radioactive minerals in rocks as geological clocks.
The relative dating techniques are very effective when it comes to radioactive isotope or radiocarbon dating.
However, not all fossils or remains contain such elements.
Geologists use radiocarbon to date such materials as wood and pollen trapped in sediment, which indicates the date of the sediment itself.Geologists often need to know the age of material that they find.They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years.To find their age, two major geological dating methods are used.These are called relative and absolute dating techniques.
