The ground is part of the planet. When you

apply a force against it, that force is going

to be teeny tiny with respect to the overall

mass of the Earth and therefore will have

no perceptible effect. When a force with

enough power is applied, the ground gets

"deformed" at and around the area where

the force is being applied (for example a

bomb crater).

It does move.

But the ground is not a solid object, it is made of small particles so the ground itself will flex and deform as a force is exerted.
