Scientists who study the ancient Earth have been working for hundreds of years to build an accurate timeline of the formation of the planet and the evolution of all life. In order to build and improve this timeline, scientists must have several types of accurate methods they can use to determine the ages of materials.

There are two main categories by which they do this: relative age dating and absolute age dating.

Imagine braving the desert heat for days or even weeks as you dig for dinosaur bones.

In relative age dating, scientists study a material and compare it to other similar materials in order to establish a timeline.

It is essentially a big sequence: This comes first, that comes next, this comes last.

Relative age allows scientists to know whether something is older or younger than something else, while absolute age means that scientists know the exact number in years that have passed since the object was created.

Relative age will require the comparison of two or more objects, whereas absolute age does not.

These strata make up much of the famous prominent rock formations in widely spaced protected areas such as Capitol Reef National Park and Canyonlands National Park.

That is, scientists cannot tell exactly how old the layers are in years to the present date, only which is older than the other.

Techniques such as radioactive dating, including carbon dating, focus more on the absolute age of an object.

Absolute dating provides a computed numerical age in contrast with relative dating which provides only an order of events.

In archeology, absolute dating is usually based on the physical or chemical properties of the materials of artifacts, buildings, or other items that have been modified by humans.
