Bristlecone pine and carbon dating

Dendrochronology, or tree-ring dating, provides absolute dates in two different ways: directly, and by calibrating radiocarbon results.

Direct Dating of Wood Cross-dating determines the age of undated wood by directly matching ring patterns with trees of known age.

They have their work cut out for them, however, because radiocarbon (C-14) dating is one of the most reliable of all the radiometric dating methods.

This article will answer several of the most common creationist attacks on carbon-14 dating, using the question-answer format that has proved so useful to lecturers and debaters. Answer: Cosmic rays in the upper atmosphere are constantly converting the isotope nitrogen-14 (N-14) into carbon-14 (C-14 or radiocarbon).

The older an organism's remains are, the less beta radiation it emits because its C-14 is steadily dwindling at a predictable rate.
