Why are dating websites good
One good example would be the elevated levels of Carbon-14 in our atmosphere since WWII as a result of atomic bombs testing.Therefore, radiocarbon dates need to be calibrated with other dating techniques to ensure accuracy.Although relative dating can work well in certain areas, several problems arise.
Plankton absorbs, Carbon-14 from the ocean much like terrestrial plants absorb Carbon-14 from the air.
It is good for dating for the last 50,000 years to about 400 years ago and can create chronologies for areas that previously lacked calendars.
In 1949, American chemist Willard Libby, who worked on the development of the atomic bomb, published the first set of radiocarbon dates.
Historical documents and calendars can be used to find such absolute dates; however, when working in a site without such documents, it is hard for absolute dates to be determined.
As long as there is organic material present, radiocarbon dating is a universal dating technique that can be applied anywhere in the world.
