Sand is a mixture because it is composed of different minerals such as quartz, feldspar, and mica. These minerals are physically combined, not chemically bonded, which means they can be separated through physical means like sifting or filtering.
Concrete is a heterogeneous mixture composed of cement, sand, gravel, and water. It is not an element or a compound.
Soil is not a compound, mixture, or element—it is a complex combination of minerals, organic matter, water, and air. It is a mixture made up of various components such as sand, silt, clay, organic material, and microorganisms.
