Sand is an example of granular material. Sand grains are generally sized between 0.0625 to 2 millimeters. The sand-forming material is silicon dioxide, but in some tropical and subtropical beaches it is generally formed from limestone. Sand has a color according to the origin of its formation. Well, how would it be if these very small sands were enlarged 110 times?
