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. See related link, below.
Sand+salt: a heterogeneous mixture.
Yes
To make salt water a heterogeneous mixture, you could add an immiscible substance such as oil or sand to the water with salt. This would create two distinct phases that do not mix evenly, resulting in a heterogeneous mixture.

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.
Mixture
it is a heterogeneous mixture (:
This mixture is not homogeneous.
When salt and sand mix with water, the salt dissolves in the water to form a solution, while the sand remains suspended. This allows the sand to be separated from the salt solution through methods such as filtration or evaporation, as the saltwater can be boiled off to leave the salt behind.
It is heterogeneous because the sand is not dissolved in the water. Apparently, the sand is still visible from the outside, unlike perhaps salt water in which the salt can no longer be seen.
Sand with shells is a heterogeneous mixture because it contains different components (sand and shells) that are visibly different and can be separated easily. In a homogeneous mixture, the components are evenly distributed and not easily distinguishable.
Heterogeneous mixtures are mixtures that can easily be separated. For instance, sand mixed with water is a heterogeneous mixture that can be separated by filtration. Another example of a heterogeneous mixture is salt mixed with pebbles, which can be separated by adding water to the mixture.
