Sand on the beach is a mixture of compounds.
Pure sand is white and its chemical name is Silicon Dioxide (SiO2)' a compound.
The red brown colour comes from iron(III) salts mixed in ther sand. The Iron(III) saltsd will also be a mixture of compounds.
First of all to correct your spelling. It is 'Concrete', not 'concrerte'. As concrete it is an heterogeneous mixture of cement, sand, gravel and water.
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.
Sand and water would be considered a heterogeneous mixture because you can see the individual components (sand and water) and they do not form a consistent composition throughout the mixture.
Sand in water is a heterogeneous mixture. The sand does not dissolve in the water, and the two components can be visibly distinguished.
the chemical formula for sand is SiO2, so it is a compound, made from Silicon and Oxygen
Iron is a chemical element; sand may be a compound or a mixture.
The purest sand is a compound, silicon dioxide. Most ordinary sand, however would contain some other materials and could be either a homogeneous or a heterogeneous mixture.

Concrete is a mixture containing cement, sand, gravel and water.
someone told me it was a mixture of clay and sand and decaying plants etc.
Mixture
Sand is a mixture and rarely is only one compound.
Sand is a mixture.
sand is a mixture because its all mixeed up with stuff!

A sand mixture is not a solution, compound, or element; it is a heterogeneous mixture. Sand typically consists of various minerals, primarily silicon dioxide (quartz), along with other materials, making it a combination of different substances. Each component retains its individual properties and can often be separated physically. In contrast, a solution is a homogeneous mixture, a compound consists of chemically bonded elements, and an element is a pure substance that cannot be broken down further.
