Final answer:
Scientists found everything intact in Pompeii after the eruption of Mount Vesuvius in AD 79, with preserved structures and plaster casts providing a snapshot of Roman life and the catastrophe.
Step-by-step explanation:
When scientists were able to search the site of Pompeii after the eruption of Mount Vesuvius in AD 79, they found everything intact.
The city was buried rapidly by a thick layer of ash and pumice, which preserved the structures and the bodies of the inhabitants in their final moments.
The use of plaster casts to fill the voids left by decomposed organic matter, including human bodies, allowed archaeologists to see the exact position of the victims, providing an extraordinary snapshot of life and tragic death in a Roman city.
