lithosphere - Coggle Diagram

- - - - Found in the lithosphere
      - Not produced by living organisms
      - Have a specific chemical composition
      - Can occur as pure elements or compounds
      - Important natural resources
- - - - A continuous process where rocks form, break down and reform.
        
        4 stages:
        
        Formation of igneous rock
        
        Formation of sedimentary rock
        
        Formation of metamorphic rock
        
        Formation of magma
  - - - About 5–70 km thick
      - Two layers:
        
        Crust: thin rocky layer + soil
        
        Upper mantle: thick rocky layer
      - Soil: rock particles + organic and inorganic materials
- - - - Rocks are mixtures of different minerals
      - Example: granite = quartz + feldspar + biotite
      - Important for human civilisation
- - - - Type
      - Formation
      - Examples
      - Igneous
      - Cooled magma
      - Granite, basalt
      - Sedimentary
      - Layers of sediment under pressure
      - Sandstone, limestone, shale
      - Metamorphic
      - Heat + pressure change existing rock
      - Slate, marble
