Sedimentary Rocks Flashcards | Quizlet

The smaller ones — known as granules — are gravel size, but still you could throw one. But you can't really throw a single grain of sand. Silt is essentially too small for individual grains to be visible, and while sand feels sandy to your fingers, silt feels smooth to your fingers but gritty in your mouth.

ZeoSand Natural Zeolite Filter Media | ZEO Inc.

ZeoSand is a natural zeolite and a highly efficient filter media that is proven for use as a sand replacement in recreational water, drinking water, and industrial applications. ZeoSand's huge surface area which is more than 100 times greater than sand traps more and finer dirt than sand. The natural molecular sieving of ZeoSand removes pollutants by ion exchange.
