INSIDE OUR EARTH, minerals on earth interiors - Coggle Diagram

- - - - 2 ignes to sediments and then to sediemntary rocks
        
        3 igne+ sedi rocks under greate pressure and heat= metamorphic
        
        4 metamorphic + very great pressu and heat = molten magma
  - - - regular and industrial purposes
    - - in industries
    - - in fertilizers
  - - - SEDIMENTARY ROCKS:
        
        igne rocks breaks down into small pieces while rollinh down hitting and this small pices are called sediments
        
        this sediments are compreswd and hardened in earths surface and forms rocks called sedimentary rocks
        
        sedimentary rocks may contain fossil(dead and decomposed) of plants, anima, micro orga
      - METAMORPHIC ROCKS:
        
        igne and sedi under greate press, heat turn into metamorphic rocks
      - IGNEASOUS ROCKS: when motlen magma solidifies and forms a hard substance called igne rocks
        
        extrusive igneseous rocks(outside earths surface)
        
        sometimes lava(molten magma) comes out from earths interior surface and falls on earth crust
        
        they cool very quickly and solidifies, rocks which are formed in this way on the earths crust is called extrusive igneseous rocks
        
        grain structure: very fine since they cool quicly
        
        ex: basalt
        
        intrusive igneseous rocks(inside earth)
        
        cools very slowly
        
        large grain stru as it cools slowly
        
        some lava cools within earths crust
        
        ex: granite
- - - - 2900km depth
      - about 84% of earths volume
      - beneath earths crust
    - - innermost layer
      - 3500km depth
      - 15% of earthsvolume
      - minerals: nickle(ni), iron(fe) nothing but ferrous and they called as nife
      - very high temp and pressure at this core
      - to reach centre of core(center of earth), dig whole of 6000km depth from oceans crust
    - - outermost layer of earth
      - thinnest of all layers
      - divi into
        
        continental crust
        
        35km deep
        
        minerals: silica and aluminium(sial)
        
        oceanic crust
        
        5km depth and above this crust there will be water
        
        silica, magnesium(sima)
      - 1% of earths volume
