The earth is NOT a solid rock. It's a very thin layer of rock, floating on top of a pool of magma, itself floating in space. The rock itself flows on all sorts of time scales as well.

A sphere will be forced by the wind, almost the same amount as any other object, regardless of its density or weight.

it's not a pool of magma, the mantle is basically solid

(except on very large timescales)
