For me to break down some of these tests into the basic is hard because there is so much to say on each one of them.
My main problem and the one point I wanted to make is that generally the only people who disagree with this science are people who actually do not understand the science.
This testing is good and accurate up to 50,000 years and is calibrated to fit in with things like climate change and human factors.
Potassium-Argon dating Works with the same principle as above.
Students understand that various dating methods — relative and absolute — have been used to determine the age of Earth. Between Earth Science and Other Disciplines: Evidence of Common Ancestry and Divergence (LS.1.1); Living Systems and the Physical Environment (LS.3.1); Nuclear Chemistry (C.1.6); Nuclear Interactions and the Conservation of Mass–Energy (P.2.3) Benchmarks: American Association for the Advancement of Science.Instead it requires the studying of the magnetic layout of say a rock.Basically the Earth goes through pole reversals in which the magnetic north pole will become the south pole and vice versa in constant looping through time.Yes of course if you are going to use Carbon dating on a sample that has no carbon then you are going to get flawed results and this cloak and dagger method is used quite a lot by skeptics.
It seems intuitive that if you want to prove or disprove a test then you would at least use it correctly so that the correct result could be scrutinized and studied for accuracy.
