erosion
The particles rub against each other and against the rock along the coast. Over time the water and the particles wear down rock into more sand. The water then carries the new sand away. Like waves, wind constantly carries sand and other small bits of earth from one place to another. Wind forms sand dunes and changes their shape.
What Is Sand? What Is It Made Of?
Sand consists of minerals and other particles ranging between roughly 0.06 and 4.75 mm. (image: Siim Sepp, CC 3.0 Unported License) At its core, sand is a granular material composed of finely divided rock and mineral particles. Technically, it's defined by size, being coarser than silt and finer than gravel.
