Because they are not chemically combined. They are physically combined and as such retain their individual properties. Mixtures are made up of substances that are physically combined and retain their individual properties.
No, sand in water is heterogeneous. Homogeneous means the same all the way through.
They are a mixture because the sand and water are not chemically combined. They retain their individual properties and can be separated by physical means, such as filtering or evaporation.
It is a mixture.
Sand in water is a mixture. Because you can differentiate between the sand and water, it is a heterogeneous mixture.

Place the mixture in water and separate the sand from the water if you want the salt. alow the water to evaporate, and you have salt and sand separated.

Not sure what is meant by mixtures? But, the sand and water can be heated to evaporate off the water, which can be condensed back into water. This will leave the sand behind.
Sand is made form a mixture of mineral grains (mainly quartz or calcite) which are themselves compounds.
Sand is not soluble in water and sand particles are settled.
Put the mixture in water and wait for all of the salt to dissolve. Then filter out the sand and wait for the water to evaporate in the sand/water solution to get the sand and salt separately.
it is a heterogeneous mixture (:
Settle it and pour off the water, or simply filter the sand out of the water.
...wet sand...?
