Question

is sand a mixture

Answer 1

Yes, sand is considered a mixture. It is primarily composed of small particles of minerals, such as quartz, feldspar, and others, along with organic materials, shells, and various other sediments. The specific composition of sand can vary significantly depending on its source, which makes it a heterogeneous mixture. Each grain of sand can have different properties, and the individual components do not chemically combine to form a new substance.
