Radiometric dating simple english
A stronger magnetic field deflects more cosmic rays away from the Earth.
Overall, the energy of the Earth's magnetic field has been decreasing, so more C is being produced now than in the past.
The rate of decay of N in 5,730 years (plus or minus 40 years).
This is the “half-life.” So, in two half-lives, or 11,460 years, only one-quarter of that in living organisms at present, then it has a theoretical age of 11,460 years.
The amount of cosmic rays reaching the Earth varies with the sun's activity, and with the Earth's passage through magnetic clouds as the solar system travels around the Milky Way galaxy.
The strength of the Earth's magnetic field affects the amount of cosmic rays entering the atmosphere.
Radiocarbon dating is one kind of radiometric dating, used for determining the age of organic remains that are less than 50,000 years old.
We will deal with carbon dating first and then with the other dating methods.In summary, the carbon-14 method, when corrected for the effects of the flood, can give useful results, but needs to be applied carefully.It does not give dates of millions of years and when corrected properly fits well with the biblical flood.Obviously, this works only for things which were once living.It cannot be used to date volcanic rocks, for example.
