This picture depicts the way Archaeologists categorize the layers of earth. Doing this helps determine how old the artifact is (i.e. if it is in one of the deeper layers of earth than we know it was more ancient; if it is in a higher layer of earth then we know it is more recent/not as old) the type of sediment it is found in can tell us a lot about the age and use of an artifact. There are different ways of testing the age of an artifact depending on what it is and where it is found. For instance Radiocarbon dating, also known as Carbon-14 dating, is a way to date the artifact to the time frame it was used.
