* Minerals are naturally occurring, solid substances with a definite chemical composition and a specific, usually crystalline, structure. Think of them as the building blocks of rocks.
* Rocks are solid, naturally occurring aggregates of one or more minerals.
Here's a simple analogy:
* Imagine building a house. The bricks, cement, wood, and glass would be like minerals.
* The house itself, made up of those materials, would be like a rock.
Here's a table summarizing the key differences:
| Feature | Mineral | Rock |
|---|---|---|
| Composition | Definite chemical composition | Mixture of one or more minerals |
| Structure | Crystalline (usually) | Non-crystalline |
| Formation | Formed by geological processes | Formed from the accumulation of minerals |
| Examples | Quartz, feldspar, calcite | Granite, limestone, basalt |
In essence, minerals are the ingredients, and rocks are the recipes. Rocks can be composed of many different minerals, and the same mineral can be found in many different types of rocks.
