Sand can be lava, coral, bones, even excrement. What’s on your favorite beach?
Depending on where you are in the world, the sand beneath your feet can be anything from a fragment of a seashell to brine shrimp excrement to a piece of coral – the classification ‘sand’ only means a particle that is smaller than gravel and larger than silt. The Amazing Life of Sand explores the diverse nature of the substance, and the incredible journeys sand particles frequently travel.
