Sand
Granular material composed of finely divided rock and mineral particles.
The bright white sands found in tropical and subtropical coastal settings are eroded limestone and may contain coral and shell fragments in addition to other organic or organically derived fragmental material, suggesting that sand formation depends on living organisms, too.
Bioerosion
Bioerosion describes the breakdown of hard ocean substrates – and less often terrestrial substrates – by living organisms.
Bioerosion of coral reefs generates the fine and white coral sand characteristic of tropical islands.
