What's even weirder is that the two "arms" are made of sand, which miraculously stays in the air...
I expect the game engine will only apply physics to blocks that are moving, and in certain cases whether those moving blocks have cascading effects on their neighbours.
Yeah, when a chunk is generated, I don't believe it necessarily makes all the sand, gravel, etc. fall. To do that for an entire chunk at once would be very computationally intensive. So, it's just generated and left hanging there. If you touch an improperly-suspended block (or an adjacent block) that will trigger it and any blocks above to react to gravity again.
