A mixture made up of different materials that can be easily separated is called a heterogeneous mixture. Here's why:

* Heterogeneous: This means the mixture has uneven composition. You can see the different components of the mixture.

* Easily Separated: The components retain their individual properties, making them easy to separate using simple techniques like:

* Filtration: Separating solids from liquids (like sand from water).

* Evaporation: Separating a dissolved solid from a liquid (like salt from water).

* Magnetic Separation: Separating magnetic materials from non-magnetic materials (like iron filings from sand).

* Decantation: Carefully pouring off a liquid layer from a settled solid (like water from oil).

Examples of Heterogeneous Mixtures:

* Sand and water

* Salt and pepper

* Oil and water

* A bowl of cereal with milk
