        Weathering of the rocks at surface
        
        Erosion and transport
        
        Deposition of sediments, burial, compaction and cementation

        Due to the pressure, the sediments squeeze together forming sedimentary rocks.

        The sediments fall into the seas, forming layers of sediments (sedimentation). Then, more layers stuck up of each other, increasing the pressure (compaction) and finaly the salt glues up all of the layers (cementation)
        
        The rocks break into smaller parts and get transported by erosive agents
        
        Erosive agents
        
        Wind
        
        Water
        
        Flows
        
        Ice
        
        Gravity
        
        Weathering is an agent that breaks up the rocks slowly into little pieces.
        
        Physical weathering
        
        The rain falls into the gaps of the rock and corross it, breaking it.
        
        Chemical weathering
        
        Polluted rain (acid rain) dissolve the rock.
        
        Biological weathering
        
        The roots of the trees break the rocks.
        
        Magma in magma chambers cool down slowly and form big crystals.
      - Extrusive
        
        The lava (magma) gets up to the surface in volcanic erupion, cooling down rapidly, forming little crystals.
      - Examples
        
        Extrusive:
        Basalt
        Obsidian
        Intrusive:
        Granite
- - - - Cheap
      - Fast
    - - Noise, air and visual pollution
      - Pollutants affect human health
      - Wildlife is driven out of the area
      - Generates highly toxic waste heaps that pollute water and soil
  - - - Has less efect on the environment
    - - Very expensive
      - Dangerous to workers
        
        The ceiling could collapse and get trapped
        
        The fumes provoke respiratory diseases
      - Gas emissions
        
        Air pollution
- - - - Near the surface, thick layer in unbroken horizontal layers
    - - More demand, less supply
    - - Easy place to look for them, little environmental issues
    - - No extreme weather
      - Close to populated areas, no need to build new roads
  - - - Deep underground, too much folding
    - - Lower demand, higher supply
    - - Extreme weather, makes mining difficult
    - - Remote places, they need to build roads
