By measuring the amount of carbon-14 remaining, scientists can pinpoint the exact date of the organism's death.

Radioactive decay: The predictable manner in which a population of atoms of a radioactive element spontaneously disintegrate over time.

Stratigraphy: Study of layers of rocks or the objects embedded within those layers.

Relative dating methods are used to determine only if one sample is older or younger than another.

Absolute dating methods are used to determine an actual date in years for the age of an object.

When carbon-14 falls to Earth, it is absorbed by plants.

These plants are eaten by animals who, in turn, are eaten by even larger animals.Absolute dates must agree with dates from other relative methods in order to be valid.The most widely used and accepted form of absolute dating is radioactive decay dating. Radioactive decay refers to the process in which a radioactive form of an element is converted into a nonradioactive product at a regular rate.Before the advent of absolute dating methods in the twentieth century, nearly all dating was relative.The main relative dating method is stratigraphy (pronounced stra-TI-gra-fee), which is the study of layers of rocks or the objects embedded within those layers.The older the pottery, the brighter the light that will be emitted.
