eli5 Why are historical/archaeology structures/evidence underground?

135 viewsOtherPlanetary Science

Earth as a whole is essentiallly a closed system right? Nothing leaves except what we send into space and (presumably) no material enters earth except the some space debris.
Where does all the earth/dirt come from to consistently bury historical structure under ground across the world?

Theres plenty of archaological sites that arent buried but the ones that get buried stay the best preserved. Sites on the surface would also get dismantled for new building materials . In some cases sites are buried for disasters like volcanoes, floods, landslides, etc but its also possible some were intentionally buried by ancient civilizations to either protect them or for use again later

there is plenty of dirt in the world on not much to bury comparatively
