What Are the Physical Properties of Sand?

2020-04-01  Sand is primarily composed of finely granulated silica and, depending on its location, can include various rock, coral, shell or lava fragments. It is lightweight and easily transported by wind and water. Its composition directly affects its color, resulting in black, white, pink and green coloring.
