Well junior that would depend on the location. See, some of the sand near coral reefs comes out of the ass of the parrot fish. So if you've been on any beach near a coral reef you got it all over you. https://www.newsweek.com/where-does...makes-white-beaches-and-now-scientists-714024
when i was 4 or 5 or 6 we had a big playground in our neighborhood. there was an older girl i liked who told me, sand would grow, just like we do, or trees. just very slowly. i bought it. this thought made my brain explode for several years, since i was wondering where all the huge rocks would go, that grew from sand. couldn't wrap my head around it. until i learned about ice being able to crack rocks into pieces, so i figured all those grown rocks would crumble again into sand. didn't solve the increased mass in that equation, but that did it for me. i still think of that today.
what's complicated about it? it was not my idea that sand grows, but maybe you can elaborate on it. i came up with an explanation why our world is not full of huge rocks. it's simple.
Pretty sure the skeleton of hard corals, sps corals? are made of calcium carbonate, and it gets broken down thru wear and tear, fish eating the fleshy parts- including Parrot fish. I think I know there is a lot of silicone as well in sand, I think. ?

Beaches. Its literally the only reason it is on the planet. All that sand in the deserts needs to be re-located to lake and ocean fronts.
Beach sand and desert sand are different. For example, desert sand is not suitable for use in concrete, unfortunately.
