When the surface area of a rock increases, what happens to particle size? ?

    Nothing, the surface area of an object has nothing to do with the size of the particles that make that object.

    When the surface area of a carpet increases, do you think the threads of the carpet change size?

    Buster is right, at least unless you are speaking literally and don't have cause and effect reversed. If the surface of a rock increased, as by accretion, the particle (rock) would increase in size, eventually becoming a boulder.

    I think you have it backwards, myself.  Particle size dictates surface area and not the other way around.  Larger particles have more surface area.  they have more volume so must have larger surface area.  Ignoring the sometimes important issue of shapes on surface area, because they are not really an issue of particle size.

    THe smaller an object the higher the surface to volume ratio. Break a rock into many small pieces, its surface area will increase.

    sorry, this makes no sense. What particles? what caused the area increase? how? did the volume or shape change? what type of rock.
