Description
Coloured scanning electron micrograph (SEM) of Coral sand (Kailua, Hawaii). Beach sand contains both rock minerals and skeletons that have been derived from living organisms (such as coral). Sand grains produced from coral have fine holes and are smoother due to wearing down by the surface action. Magnification: x43 when shortest axis printed at 25 millimetres.
