Now something serious. How are all these towns covered up? I thought it took millions of years to make 1 inch of topsoil.
I have no clue
The winds of time blow sand, dust, dirt at a rate of a few feet every hunderd or so years; a prime example of this can be found in Isreal when visiting the Crusader Castles. You can see how during unoccupied periods between Crusades that the sand built up and when the next group came into the fortifications, they literally built up from that level a newer and higher level, which was done a total of three times.
That’s not serious, that’s just stupid.
