Here are some examples:

* Sand and water: The sand settles to the bottom, forming a solid phase, while the water remains liquid.

* Oil and water: These two liquids do not mix, so they form separate layers.

* Salt and pepper: You can easily see the individual grains of salt and pepper.

* A salad: The lettuce, tomatoes, cucumbers, etc., are all distinct and visible.

* A bowl of cereal: The cereal, milk, and fruit are all separate phases.

Key characteristics of heterogeneous mixtures:

* Multiple phases are visible.

* Components can be easily separated.

* Composition is not uniform throughout the mixture.
