The atmosphere contains many stable carbon atoms and relatively few radiocarbon atoms.
The ratio of radiocarbon to stable carbon atoms in the atmosphere has varied in the past.
This procedure of radiocarbon dating has been widely adopted and is considered accurate enough for practical use to study remains up to 50,000 years old.
When it comes to dating archaeological samples, several timescale problems arise.Geology is the study of the composition and physical properties of rocks, minerals, gems and other related earth materials, including diamonds and crystals.Scientists gain an understanding of the Earth's history by studying its composition.More recently is the radiocarbon date of 1950 AD or before present, BP.There are two techniques for dating in archaeological sites: relative and absolute dating.
