Why would sand and water be an example of a heterogeneous ...

If the mixture was homogenous, you would have to get down to the level of atoms and molecules before you could find areas that are all sand or all water. Also, because sand is insoluble in water and is much heavier than water, it is very easy to separate them. Also, if there is enough water, the area near the top of the water will have no sand.

Why is sand in water a mixture - science.answers.com

Sand can be settled out of water as well, as the sand is heavier than water. . Easiest is by filtering. A fine mesh or cloth would catch thesand particles and let the water through. . Or simply let the mixture settle. Sand is heavier, and will sinkto the bottom, leaving a clear layer of water to be siphoned offfrom the top. . Or distill it.
