Absolute and relative dating techniques

Egyptologists, for example, created a relative chronology of pre-pharaonic Egypt based on increasing complexity in ceramics found at burial sites.

This includes factoring in many variables, such as the amount of radiation the object was exposed to each year.

These techniques are accurate only for material ranging from a few thousand to 500,000 years old — some researchers argue the accuracy diminishes significantly after 100,000 years.

Measuring carbon-14 in bones or a piece of wood provides an accurate date, but only within a limited range.
