In a stratigraphical context objects closer to the surface are more recent in time relative to items deeper in the ground.

Although relative dating can work well in certain areas, several problems arise.

There are two techniques for dating in archaeological sites: relative and absolute dating.

Relative dating stems from the idea that something is younger or older relative to something else.

Radiocarbon is then taken in by plants through photosynthesis, and these plants in turn are consumed by all the organisms on the planet.

So every living thing has a certain amount of radiocarbon within them.

As long as there is organic material present, radiocarbon dating is a universal dating technique that can be applied anywhere in the world.

It is good for dating for the last 50,000 years to about 400 years ago and can create chronologies for areas that previously lacked calendars.

Absolute dating represents the absolute age of the sample before the present.
