Stratigraphy is the science of understanding the strata, or layers, that form the sedimentary record.

Strata are differentiated from each other by their different colors or compositions and are exposed in cliffs, quarries, and river banks.

C-12 is by far the most common isotope, while only about one in a trillion carbon atoms is C-14.

C-14 is produced in the upper atmosphere when nitrogen-14 (N-14) is altered through the effects of cosmic radiation bombardment (a proton is displaced by a neutron effectively changing the nitrogen atom into a carbon isotope).

When a creature dies, it ceases to consume more radiocarbon while the C-14 already in its body continues to decay back into nitrogen.

"Everything which has come down to us from heathendom is wrapped in a thick fog; it belongs to a space of time we cannot measure.

Plants and animals naturally incorporate both the abundant C-12 isotope and the much rarer radiocarbon isotope into their tissues in about the same proportions as the two occur in the atmosphere during their lifetimes. What effect would the declining strength of the earth's magnetic field and a catastrophic worldwide flood have on radiocarbon dates?The radioactive carbon has six protons and eight neutrons in its nucleus, giving it a total atomic mass of 14.These rocks normally form relatively horizontal, parallel layers, with younger layers forming on top.

If a fossil is found between two layers of rock whose ages are known, the fossil's age is thought to be between those two known ages.

This atom is not stable, and will break down, releasing nuclear energy in the process.
