Or you can tell that certain parts of the Moon's surface are older than other parts by counting the number of craters per unit area.

The old surface will have many craters per area because it has been exposed to space for a long time. If you assume that the impact rate has been constant for the past several billion years, then the number of craters will be proportional to how long the surface is exposed.

Radiocarbon dating is one such type of radiometric dating.

A process for determining the age of an object by measuring the amount of a given radioactive material it contains.

In radioactive atoms the nucleus will spontaneously change into another type of nucleus.

When looking at a large number of atoms, you see that a certain fraction of them will change or dating system because you can determine accurate ages from the number of remaining radioactive atoms in a rock sample.

C) dating usually want to know about the radiometric[1] dating methods that are claimed to give millions and billions of years—carbon dating can only give thousands of years.

It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.We will deal with carbon dating first and then with the other dating methods.
