When finding the age of an organic organism we need to consider the half-life of carbon 14 as well as the rate of decay, which is –0.693.

These tracks are believed to have been made by amphibians or primitive reptiles.

Sediments appear in many places to be thin beds spread over wide areas in short periods of time. At its base, the limestone is interbedded with green shale and sandstone.

Granites of this sort are associated with uplift and formation of mountain ranges. Formed by metamorphism of rocks that were originally sedimentary.

The metamorphism occurred after the rocks were buried to great depth by mountain building.

The relationship is non-linear, involving some sort of logarithm or exponent.

The mathematical formula can be used to determine exactly how many half-lives have elapsed, for any fraction of parent/daughter isotope, without having to make a visual estimate from a graph.

After 5,730 years, the amount of carbon 14 left in the body is half of the original amount.
