* Minerals: These are naturally occurring, solid substances with a specific chemical composition and a defined internal structure. Think of them like the building blocks of rocks. Examples include quartz, feldspar, and calcite.
* Rocks: These are naturally occurring solid aggregates of one or more minerals. Think of them as the "houses" built from mineral "bricks."
Here's why all rocks are made up of minerals, but not all minerals are rocks:
* Rocks are made of minerals: Rocks are formed from the accumulation and cementation of mineral grains. The type of minerals present determines the rock type. For example, granite is made of quartz, feldspar, and mica.
* Not all minerals are rocks: While minerals are the building blocks of rocks, some minerals can exist independently without being part of a larger rock structure. Think of a single quartz crystal – it's a mineral, but not a rock.
In summary: Think of it like LEGO blocks. The individual blocks are the minerals, and the structures you build with them are the rocks.
