Ancient myths and legends tell of several mysterious underground cities filled with secret chambers, passages shrines and tombs. Many of these remarkable underground worlds remain shrouded in mystery because we have not been able to locate them yet.
This is more of an archeology question, but hopefully someone here can help explain. I've always been kind of puzzled thinking about how ancient cities or ruins get buried. More specifically, I have a few questions. How deep down are most ancient remains when they are found (depends on age and location, of course)? What is the natural rate of sediment deposit and where does it come from? How do cities that are continuously inhabited (like Rome) get buried? In the past people have told me that when buildings fell down, it was common practice for people would fill them in with dirt and build over them.
