Similarly, materials of human origin are also deposited onto the earth’s surface.In archaeological sites, natural and human-generated materials occur together in layers.These layers, called strata, form a record of past events that archaeologists analyze and interpret.

Archaeologists have access to various techniques for dating archaeological sites or the objects found on those sites.
Portable objects that are used, modified, or created by human activity. An artifact's physical property, such as the material(s) from which the artifact is made, its size, shape, function, and decoration.
Covering an archeological site with fill to stabilize and preserve it.
This approach helps to order events chronologically but it does not provide the absolute age of an object expressed in years.
