- - - - most of the interior of the Earth
      - peridotite
      - solid but soft
    - - hottest part
      - Two parts
        
        Outer core
        
        Inner core
      - iron and nickel
    - - Thinnest layer
      - There are 2 types
        
        continental crust
        
        oceanic crust
  - - - Fracture : breaks intoirregular fragments
      - Cleavage: breaks into regular fragments
      - how a mineral breaks when hit
    - - resistance to breaking if it hit deformed
      - breaks easly : brittle
      - If not : tough
    - - For example
        
        Sulphur
        
        Malachite
      - several colors
      - characteristic color
      - For example : Quartz
    - - resistance
      - mohs scale
    - - For example
        
        Quartz
        
        Pyrite
      - geometric shape a mineral's particles show
    - - reflects light
