Final answer:
An undisturbed grave is a burial site that remains in the same condition since the original burial, while a disturbed grave has been altered or tampered with after interment.
Step-by-step explanation:
In the context of archaeology or forensic anthropology, the terms undisturbed graves and disturbed graves refer to the state of a burial site. An undisturbed grave is one that has remained in the same condition as when it was initially made, with no signs of the soil being moved or the contents having been tampered with since the original burial. In contrast, a disturbed grave is one that has been altered or tampered with after the initial interment, which could include signs of grave robbing, legal exhumation, natural events, or even archaeological excavations.
For example, archaeologists might find an undisturbed grave with artifacts and human remains in the positions they were originally placed. On the other hand, a disturbed grave might show evidence of soil disruption, missing items, or human remains that have been displaced from their original locations.
