Sand Pebble

Sand

Sand is a granular material composed of finely divided mineral particles. Sand has various compositions but is usually defined by its grain size. Sand grains are smaller than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass.

Pebble

A pebble is a clast of rock with a particle size of 4–64 mm (0.16–2.52 in) based on the Udden-Wentworth scale of sedimentology. Pebbles are generally considered larger than granules and smaller than cobbles. Pebble tools are among the earliest known man-made artifacts, dating from the Palaeolithic period of human history.

Desert sand (color)

Desert sand is a very light and very weakly saturated reddish yellow color which corresponds specifically to the coloration of sand. It may also be regarded as a deep tone of beige.
