As an object slides across a rough horizontal surface, what happens to the object's gravitional potential energy with respect to the surface and speed?

Would't potential energy decrease at rest?

    How can GPE decrease on a horizontal surface? The distance to the center of the Earth is the same, that is what determines GPE.
    GPE does not change on the horizontal surface.

    Would speed increase?

    I know speed would increase when potential energy decreases but in this case its different. Therefore, if potential energy is remaining the same wouldnt speed remain the same too
