Why Is Radiocarbon Dating Important To Archaeology? It is formed hh up in the atmosphere by cosmic radiation coming from outer space. The newly formed carbon-14 has hh energy at the moment of its formation, so that it rapidly oxidizes to carbon dioxide, which spreads out and distributes itself evenly in the atmosphere. Archaeology has the ability to open unimaginable vistas of thousands, even millions, of years of past human experience.” – Colin Renfrew. When it comes to.
