No water in your bath or in the containers that the oceans are in...etc, not to mention everything else falling apart that wasn't buried deep.
Try it all on a football and see what happens.
Bridges are horizontal, sky scrapers are vertical. You would still build plumb to the ground so difference in a densely built up area is imperceptible to the naked eye.
A long bridge will account for curve because it's horizontal.
