The textbooks speak of the radiometric dating techniques, and the dates themselves, as factual information.Carbon-14, or radiocarbon, is a naturally occurring radioactive isotope that forms when cosmic rays in the upper atmosphere strike nitrogen molecules, which then oxidize to become carbon dioxide.Green plants absorb the carbon dioxide, so the population of carbon-14 molecules is continually replenished until the plant dies.Uniformitarian geologists use so-called dating methods to determine the ages of the surrounding rocks.Certain types of rocks, especially those that form from magma (igneous), contain radioactive isotopes of different elements.
