Sand is a mixture, not a compound. Sand is classified as a heterogeneous mixture because it does not have the same properties, composition and appearance throughout the mixture. A homogeneous mixture has a uniform mix throughout.
Sand is found over much of Earth's surface, blanketing beaches, riverbeds and deserts. It is made up of small particles of rock, minerals and other materials.
