The stages of sand grains include immature, young, old, and mature. Sand that isn't quite mature has a lot of clay, and it also has a lot of broken grains. Sand that has reached maturity lacks clay and has fewer sharp edges.
When viewed up close, individual sand grains, which have a diameter of less than one millimeter, resemble tiny jewels. The quartz, feldspar, and mica fragments that make up granitic mountain sand are frequently angular in shape. Large sand hills known as dunes are created when powerful winds gather the tiny grains of desert lake bottoms and river deltas. Some sand dunes develop smooth, rounded grains that resemble small stones in a rushing stream after many millennia of rubbing against one another. Sometimes unusual humming or booming sounds, resembling a telegraph line or squadron of World War II fighter jets, are created as these polished grains move over one another.
