How do scientist do carbon dating

Radioactive decay occurs at a constant rate, specific to each radioactive isotope.

Since the 1950s, geologists have used radioactive elements as natural "clocks" for determining numerical ages of certain types of rocks. "Forms" means the moment an igneous rock solidifies from magma, a sedimentary rock layer is deposited, or a rock heated by metamorphism cools off.

You've probably heard scientists talk about things that they claim are millions, if not billions, of years old, though.

Radioactive elements were incorporated into the Earth when the Solar System formed.

When it collides with an energetic neutron it becomes carbon-14, with six protons and eight neutrons and gives off a hydrogen atom with one proton and zero neutrons. Carbon-14 is an isotope of carbon, which exists only is small amounts in the environment (1 in one trillion carbon atoms is carbon-14).

The ratio of carbon-14 to carbon-12 in the atmosphere and on earth is nearly constant, although there has been some change in carbon-14 concentration over the last 10,000 years.

Carbon-14 formed in the atmosphere can combine with oxygen to form carbon dioxide (CO2).

Carbon-14 in the bodies of animals and plants is constantly decaying.

However, the decaying carbon-14 is constantly being replaced as the plant or animal consumes more carbon-14 from the air or through its food.

Carbon-14 is created from nitrogen-14 in the upper atmosphere of the earth.
