ROCKS, : - Coggle Diagram

- - - - rock praticals become layer of segment.
- - - - characteristic
        
        Distincly layered easy to crumble
      - formation
        
        Through compacts of sediments
        
        Rocks that have been changed from heat and pressure
        
        Forms deep in the earth
        
        You can often see minerals in these rocks
      - types
        
        Chemical (Compaction of dissolved minerals)
        
        E.g Iron ore ,rocksalt
        
        Organic(Compaction of organic materials)
        
        E.g Coal, limestone
        
        Clastic (compaction of broken rocks)
        
        Eg Sandstone ,Conglomerate.
      - Uses
        
        Production of chalk,lime ,industrial Carbon dioxide
    - - characteristic
        
        May or may not have layers, relatively harder
      - formation
        
        Through transformation of older rocks
        
        often forms at the bottom of the body of the water
        
        we can often see fossils or other rocks in this rocks
      - types
        
        Foilated(Distinguished by layers)
        
        E.g Slate,Phylitte
        
        Non foilated(no distingusable layers)
        
        E.g Marble, Quartine
      - Uses
        
        Manufacture of Slate,sculpture material
    - - formation
        
        can have crystals air bubbles or glassy surface
        
        most of the earth's crust are made up of this rock
        
        Through solidification of magma or lava
      - types
        
        extrusive(rapid cooling of magma)
        
        e.g pumice, basalt
        
        Intrusive(slow cooling of magma)
        
        eg :granite,diorite
      - characteristic
        
        no layers hardest of all
      - Uses
        
        Construction of buildings,Floorings and interior
