yes. You have the solid phase (mostly SiO2) and a gas phase in between (air)
Sand and pebbles
Wet sand is considered heterogeneous because it contains a mixture of different-sized particles that are not uniformly distributed.
Oil and water. Sand and water.
We can found homogenous sands but also heterogenous sands.
No because the pieces of sand were the same so that would be a homogenous mixture. Heterogenous mixtures are noticeabley different from one another. Thank you very much :)
Sand, for the most part, is homogeneous. If you go to the beech, the particles of sand are of uniform size and chemical composition. Although you might find a foreign object, such as a coin, an article of jewelry, a cigarette butt, or a piece of shell, sand is very consistent and uniform; therefore, it is homogeneous.
Sand free sea water is homogeneous.
It is neither heterogenous nor heterogenous. It is HOMOgenous
Soil is a heterogeneous mixture because it is made up of various particles and components such as sand, clay, organic matter, water, and air. These components are not uniformly distributed throughout the soil, resulting in a non-uniform mixture.
Yes. A heterogeneous mixture is one that lacks uniformity. When salt water (a homogeneous mixture) and sand are placed in the same container, the sand sinks to the bottom and the salt solution remains, largely, above the sand, demonstrating the characteristic lack of uniformity.

Mixtures.
Gasoline is a homogeneous solution.
