I was curious since mass would seem lopsided. I guess not enough. Thanks for answering.
My layman's understanding is that the water mostly makes up for it, and that more wobble comes from the moon than any inconsistency in land-mass distribution
The crust of the earth is relatively thinner than the skin of an apple from my understanding. So I wouldn't expect anything happening on the crust to have a huge impact on that kind of behavior. Granted, even small changes could be noticable.
That's a great point. When it comes to the Earth's mass, the surface is barely a factor.
