we see the algae die and make a white layer on the lake bottom.3.We have no reason to think that the white layers are formed in any other way.4. With this, we can then count the white layers to get what year the white layer was deposited.This method also works on some inorganic compounds, as long as they also assimilated carbon-14 during their formation.Libby confirmed the accuracy of radiocarbon dating by comparing his results with the known age of tree ring samples.
