* Solid solution: This means the different minerals that make up granite are uniformly distributed throughout the rock. You can't easily separate them with a simple process like filtering.

* Heterogeneous mixture: While the minerals are uniformly distributed, they are still distinct components. You can see the different colors and textures of quartz, feldspar, mica, and other minerals that make up granite.

Other examples of rocks that are solid mixtures:

* Sandstone: A mixture of sand grains (mostly quartz), cemented together.

* Conglomerate: A mixture of rounded pebbles, gravel, and sand, cemented together.

* Schist: A metamorphic rock with visible layers of different minerals.

* Gneiss: Another metamorphic rock with visible bands of different minerals.

It's important to note that all rocks are essentially mixtures, but the type of mixture (solid solution, heterogeneous mixture) and the specific components determine their classification.
