This Catalyst article explains how studying sand can reveal both the geological and biological history of a local environment as sand varies from place to place. Sand from near a copper smelter can contain grains of copper; grains can contain worm trails from microscopic worms living in the ocean. Even the grains themselves can contain clues as to where they are from – grains from a desert environment tend to be pitted and pock-marked from where they collide with each other whereas grains from the ocean tend to be worn to a smoother surface.
