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?
In: Planetary Science
Have you ever seen a sidewalk that was freshly edged after grass/etc started pushing soil over the edge and then growing in that soil? That process, but for decades or centuries, or even thousands of years.
Also: wind can blow sand, floods can bury stuff with mud, volcanoes, etc.
