Because sand is a granular substance made up of minute particles of rocks or minerals, it is a heterogeneous combination. A heterogeneous mixture is one in which the components are not uniformly distributed throughout the mixture.
Sand, for example, can have a variety of grain sizes as well as microscopic coloured particles. Blood, gravel, and a mixture of oil and vinegar are all examples of heterogeneous mixes.
Because an element, such as potassium, consists of just one sort of atom, sand cannot be classified as an element. Sand, on the other hand, is not a compound. Compounds are substances that are made up of two or more elements joined by a bond. A compound’s components are also in a specific proportion. Sodium chloride and water are two examples of compounds.
