The current model for making sand is pretty simple. Start with a mountain, a big sucker of a rock. Then the daily transition between warm day time and colder night time, and between hotter summer and colder winter will cause expansion and contraction of the rock, gradually over long periods of time opening small cracks.
Again over time, water will fill the cracks and when it freezes enlarge the cracks, eventually breaking off pieces.
Again, over time the pieces are transported from higher elevations to lower ones by wind, water and gravity. During transportation they are broken up further, becoming smaller and smaller pieces.
Nothing is needed other than processes we can see at work today and lots of time.
So what is a Flood model for making sand?
