Why is it that you can break apart the hydrogen bonds between water molecules and they will conjoin again when they are brought close to each other but the same principle doesn't work for the bonds in things like rocks. If a rock is broken in two, why won't the bonds form again. (At least in normal temperatures, if that has anything to do with it.)

It may help to think of the general chemical AND physical properties of fluid and solid phases.
