heavier atoms are even less subject to these minute changes, so the dates of rocks made by electron-capture decays would only be off by at most. When this does happen, it is usually because the gas within bubbles in the rock is from deep underground rather than from the air. Varves can be harvested by coring drills, somewhat similar to the harvesting of ice cores discussed above. First edition 1994; revised version 2002.

Non-Radiometric Dating Methods for the Past 100,000 Years We will digress briefly from radiometric dating to talk about other dating techniques. This paper is available on the web via the American Scientific Affiliation and related sites to promote greater understanding and wisdom on this issue, particularly within the Christian community. Their results consistently agree with an old Earth.

Snoke, an elder in the Presbyterian Church (PCA) and a Physics professor, presents a strong case for a geologically old Earth. A halo would build up over a long period of time even though the center of the halo never contained more than a few atoms of polonium at one time. Whether it is indeed intended to represent a horse, or some other creature instead, has been debated, but it has certainly been called a horse since at least medieval times. The potassium-40 content of the sample is found by multiplying the argon-39 by a factor based on the neutron exposure in the reactor. A half-life is more easy to define than some point at which almost all of the parent is gone. In the next interval, with only a fourth remaining, only one eighth of the original total will decay. Radiometric dating is based on the half-lives of the radioactive isotopes. It is possible to date some rocks by the potassium-calcium method, but this is not often done because it is hard to determine how much calcium was initially present.
