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

The nucleus of every radioactive element (such as radium and uranium) spontaneously disintegrates over time, transforming itself into the nucleus of an atom of a different element.

In the process of disintegration, the atom gives off radiation (energy emitted in the form of waves). Each element decays at its own rate, unaffected by external physical conditions.

The age of the remains of plants, animals, and other organic material can be determined by measuring the amount of carbon-14 contained in that material.

Carbon-14, a radioactive form of the element carbon, is created in the atmosphere by cosmic rays (invisible, high-energy particles that constantly bombard Earth from all directions in space).

Dendrochronology: Also known as tree-ring dating, the science concerned with determining the age of trees by examining their growth rings.

Half-life: Measurement of the time it takes for one-half of a radioactive substance to decay.When the organism dies, the supply stops, and the carbon-14 contained in the organism begins to spontaneously decay into nitrogen-14.The time it takes for one-half of the carbon-14 to decay (a period called a half-life) is 5,730 years.By measuring the amount of original and transformed atoms in an object, scientists can determine the age of that object.Cosmic rays: Invisible, high-energy particles that constantly bombard Earth from all directions in space.When carbon-14 falls to Earth, it is absorbed by plants.
