Secrets of the Sand

Seeking Saltwater Sand Week

Composed mainly of quartz, feldspar and mica, sand is the product of many finely ground rocks. The colour of sand is determined by its component rocks and can vary from near black to pink and yellow.

Sand is constantly being moved by the water of rivers and seas. Constructive swells bring sand to the shore and destructive swells take it away.

Acting as a veritable microclimate, sand is also home to a wide range of living organisms. Crabs, clams and beach hoppers are but a few of the more popular residents. Not every sand dweller is as popular though. Inhabitants such as the weever fish are cursed by surfers up and down the British shores for their stings.
