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.

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.

Since certain species of animals existed on Earth at specific times in history, the fossils or remains of such animals embedded within those successive layers of rock also help scientists determine the age of the layers.
