Carbon dating magnetic field changes
Climate science required the invention and mastery of many difficult techniques.These had pitfalls, which could lead to controversy. Using the largest set of radiocarbon dates ever obtained from a single Maya site, a team of archaeologists have developed a high-precision chronology that sheds new light on patterns leading up to ...The extent and depth of lakes in glaciated regions of North America are controlled by climate and the influence of differential isostatic rebound of the land's surface that began when Pleistocene ice ...
Ironically, given how supposedly useless carbon dating is claimed to be, Creation Ministries International rests part of their "101 Evidences" on carbon dating being a useful method for within several thousand years.
In earth and environmental sciences, radioactive isotopes, atom variants that decay over time, play a major role in age determination.
A radioactive isotope of the inert gas argon 39, for example, is ...
The radioactive isotope carbon-14 is created in the upper atmosphere when cosmic-ray particles from outer space strike nitrogen atoms and transform them into radioactive carbon.
Some of the carbon-14 might find its way into living creatures.
