I think both Spypet and Momotaro are slightly overstating.
If you try putting a layer of sand on top a layer of gravel, left undisturbed, the sand will work itself into the spaces between the gravel particles, but will not raise the gravel to the top layer.
If you try putting a mix of sand and gravel, undisturbed, the sand will work its way slowly downwards to fill gaps between gravel, this will leave the gravel portion of the mix without sand on the top.
If you have a choice, you have a problem, till you elect your choice. No choice, no problem, only consequences, learn to live with them.
