Why are archaeological sites buried?

Answer 1

well, because dirt blows from one place to another, and different things happen... earthquakes floods, etc, that all move dirt from one place to another. Over time, whole cities can be buried, and new ones built on top. Dinosaur bones and other things of arcaeological interest all get buried... or eroded away, washed away, and buried somewhere else. So, when we want to look at things from a long time ago in history, we usually have to dig them up.

Archaelogical sites are buried because they are, for the most part, ruins of ancient civilizations that existed long ago. Civilizations die out and leave ruins in their wake because of other nations/peoples conquering them and moving them, or if they are deemed not worthy of saving (or if they are savage brutes who dislike hostages and slaves), they are killed and the place is leveled or burnt to the ground. In rare occasions, peoples move from one permanent location to another, which have led amateurs to believe that they died out, though they might have died out or were the victims of genocide in some other location. In even more rare occasions, towns and cities were burned to the ground and utterly destroyed by fiery rock and sulfur from heaven for very specific reasons, such as the case with Sodom and Gomorrah in The Bible. In addition to the above we have natural disasters, like the volcanic eruptions of Thira that caused the extinction of the Minoan civilization [1450 BC] and Vesuvius that buried the cities of Pompeii and Herculaneum [79 AD] in the times of the Roman Empire. Do not forget the floods that are reported in the Greek Mythology, Ogygos, Pyrrha and Deucalion and/ or the Bible [Noah's deluge] that brought an unexpected end to all civilized activity of the known world of the respective times. Human activity, as it is a custom to use construction material existing in the vicinity to build new temples and buildings after new settlers arrive in a destroyed area. It did happen at the Pyramids of Egypt that once were covered by lime. As it happened with the ruins of the ancient Greek temples that the original material was used to build the temples of the new religion [Christians]

Answer 3

Archaeological sites can become buried over time due to natural processes such as sediment deposition, erosion, and vegetation growth. Human activities, such as construction, can also bury archaeological sites. The accumulation of layers of soil and debris can gradually cover and protect these sites, preserving them for future excavation and study.
