And if there is that amount of water beneath the surface, more than all surface water, then sometime, somewhere, something would give and the land would sink and there would be a huge ass friggin hole somewhere...

No such illustrations have ever appeared in any halfway reputable textbook. Your memory is playing tricks on you.
