Gravitational pull is directly related to mass. It pulls just as hard on a tonne of water as it does on a tonne of rock.

A tonne of water takes up more space, as it is less dense. And indeed, the gravitational pull over a large rock formation is higher than over the deep ocean, as all that rock adds its own mass to the pull. That will easily make for a few hundreds of a % difference.

The gravitational constant isn't a constant anymore either!
Scientists determined it has systemic variance.
Something is messing with our gravity...
