3.1: Minerals
- A naturally occurring usually inorganic solid that has definite crystalline structure and chemical composition
- Elements: Pure substances that cannot be broken down into simpler substances
- Atom: The building blocks of matter
- Compounds: When a substance is made out of two or more elements
- Finding out if its a mineral
- Must be inorganic
- Must have crystalline structure
- Naturally Reoccurring
- How it's formed:
- Magma and Lava
- The heat from lava and magma can make rocks join together
- Metamorphism
- When temperature and pressure change a rock
- Evaporation
- When a liquid evaporates, the solid comes out of the solution
- Classification
- Silicate Minerals: When a mineral is composed out of silicate tetrahedrons and other elements
- Non silicate Minerals: Not containing a silicate tetrahedron
- Native Elements: Only made up of one element
- Halides: When fluorine or chlorine combine with calcium
- Sulfates: Minerals that contain sulfur and oxygen
- Carbonates: When minerals contain carbon and oxygen
- Oxides: When compounds form when there is aluminum or iron combines with oxygen
- Sulfides: Minerals that contain one or more elements such as lead, or iron, combined with sulfur
