The amount of carbon-14 in the atomosphere is, on an average, relatively constant.
Plants take in carbon-14 through the process of photosynthesis.
Founded in 2002 by Nobel Laureate Carl Wieman, the Ph ET Interactive Simulations project at the University of Colorado Boulder creates free interactive math and science simulations.
Ph ET sims are based on extensive education research and engage students through an intuitive, game-like environment where students learn through exploration and discovery.
This is the second lesson in a three-lesson series about isotopes, radioactive decay, and the nucleus.
There are three main assumptions that must be made to accept radiometric dating methods.
These must be accepted on faith in uniformitarian and naturalistic frameworks.
Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed.
The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.
