Part Science / Part History: Still don't understand the physical process which results in Ground Level being raised after successive Centuries / Millennia... for example why don't we find Ancient Rome crumbling right next to Modern Rome instead being buried underneath as it now is...?

by New_Pakistani

How does ground level physically get raised over time?

The only reply I seem to get is that 'cities get built on top of each other' or 'another layer gets added on top.'

But how does this actually happen physically?

How can you physically build a layer on top of another layer...?

Or does the ground sink, all at the same time...?

Or are some layers underground while others are out in the open...?

You might find this thread helpful: Why does so much archaeology end up underground?

It has two excellent answers by /u/kookingpot and /u/alriclofgar

There's more to be said, and surely in more detail, but look at the answer by /u/kookingpot right here. Hopefully this may summon them, as they've written on it both here and in r/AskScience if not other places. Archaeology and anthropology (see r/AskAnthropology) also might have insight.

I would ask this at r/AskScience because it's more geology then history.
