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.
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.
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]
The Archaeological Resources Protection Act of 1979 (ARPA) improved enforcement against vandalism, unauthorized excavation, and trafficking of artifacts from federal archaeological sites. It regulates the excavation and removal of archaeological resources, as well as the buying and selling of artifacts to prevent looting and preserve cultural heritage.
The National Park Service (NPS) is responsible for the management and protection of archaeological and historical sites in the United States. The NPS works to preserve these sites and make them accessible to the public for educational and recreational purposes.

Alfred Marche contributed to Philippine archaeology by conducting excavations and surveys in several archaeological sites across the Philippines in the late 19th century. His work helped to document and record prehistoric and historic sites, artifacts, and cultures in the country, providing valuable insights into the archaeological history of the Philippines. Marche's efforts laid the foundation for further archaeological research and study in the region.
Archaeological field work may uncover sites such as prehistoric settlements, ancient burial grounds, temples, forts, and shipwrecks. These sites can provide insight into past societies, culture, trade routes, technologies, and religious practices. Excavations of these sites can help archaeologists piece together the history and lifestyle of past civilizations.

Two of the most famous archaeological sites in Egypt are the Great Pyramid at Giza and Amarna, the ruined capital of the heretic pharaoh Akhenaten.
In Archaeology Forensic Pathologist examine bodies or human remains found at the site, determine the cause of death and how, why they buried. This may explain the fate of the site or the even its purpose.
A biological anthropologist would typically examine human remains found at archaeological sites. They study aspects like biological variation, health, and behavior of past populations by analyzing bones and teeth.
well there are so many that no they are one of the dig sites selected
Clay pots and vessels are fragile and can break easily due to their age, burial conditions, and handling during excavation. Additionally, the pressure of layers of soil and debris over time can cause them to crack or shatter. In archaeological sites, the sheer number of artifacts and the process of overlapping habitation layers can also contribute to the high frequency of broken pots and vessels.

An archaeological horizon is a distinct layer within a site that shares specific cultural artifacts, features, or characteristics. It represents a particular period or culture within the site's history and helps archaeologists understand the chronological sequence of human activities at that location.
