- - - - VOLCANIC CHIMNEY : CENTRAL VOLCANO
      - FISSURES: LATERAL
- - - - ICELANDIC TYPE
- - - - fragmentary volcanic rocks ejected into the air
      - VOLCANIC ASHES, LAPILLI, VOLCANIC BOMBS
    - - THESE FACTORS AFFECTS MAGMA'S VISCOSITY
        
        LAVA APPEARANCE DEPENDS ON VARIOUS FACTORS: COMPOSITON, QUANTITY OF GAS CONTEINED, EARTH MORPHOLOGY
  - - - SHIELD VOLCANOES:
        
        THE LARGEST VOLCANOES ARE SHIELD TYPE
        
        LARG VOLCANIC BUILDINGS AND THEIR SHAPE RECALLS A SHIED RESTING FLAT ON THE GRAUND
        
        FLUID LAVAS (CONTAINS LITTEL SALICA) AND THE FLOWS THEREFOR ESPAND OVER VERY LARGE AREAS
        
        LAVAS CONTEINS SMALL QUONTITIES OF GAS AND VAPORS THEREFOR ERUPTIONS ARENT VIOLENT
        
        INDIA, OCEANS
      - LAYER VOLCANOES:
        
        CONE-SHAPED VOLCANOES WHIT STEEP SIDES
        
        LAVA IS NOT VERY FLUID
        
        DEPENDING ON THE VISOSITY THIR ACTIVITY CHANGE FROM REGULAR JETS TO VERY VIOLENT EXPLOSIVE ERUPTIONS
        
        JETS OF GASESS COMES OUT CARRYING ASH AND LAPILLI DESCENDS ALONG THE FLANKS AT VERY HIGH SPEED
      - VOLCANIC BUILDINGS HAVE VERY DIFFERENT SIZES
      - THERE ARE ALSO OTHER STRUCTURES FROM VOLCANIC ACTIVITIES: CALDERAS, SLAG CONES
        
        CALDERAS: LARG CIRULAR DEPRESSIONS, ONCE THE ERUPTION ENDS AND THE MAGMA CHAMBER IS EMPTY THE VOLCANO IS NOT ABLE TO SUPPORT IT'S ROOF THAT COLLAPSES, OCCUPIED BY A LAKE FORMED BY RAINWATER
        
        SLAG CONES: REGULAR FRAGMENTS OF SOLIFIED LAVA, RELATIVELY SMALL AND HAVE A DEEP CENTER AT THE TOP, FOUNDED NEAR LARGE VOLCANOES
- - - - LAHARS
        
        VOLCANIC MUDSILDES
        
        MUD CASTINGS
        
        FORMED WHEN ASHES MIXES WITH RAINWATER
      - TSUNAMI
        
        HUGE WAVES GENERETES BY THE COLLAPSING OF SLOPES OF VOLCANIC ISLANDS
      - GAS EMISSION CAN VE VERY DANGEROUS AS WELL
        
        ESPESIALLY CARBON DIOZIDE ONES CALLED MOFETES
        
        THEY CAN ALSO OCCUR DURING THE QUIESCENT PHASES
  - - - JETS OF STREAM AND VERY HOT WATER EMITTED AT REGULAR INTERVALS THAT COMES OUT OF THE GRAUND FORCEFULLY
    - - QUIETER HOT WATER SPILLS
- - - - MANTEL IS SITUATED DEEP DOWN BETWEEN 75 AND 250 KM
      - AS SOON AS MAGMA REACHES THE SURFACES IS CALLED LAVA
        
        MAGNA AND LAVA DO NOT HAVE THE SAME CHEMICAL COMPOSITION SINCE MAGNA DURING THE ERUPTION RELEASES GASES INTO THE ATMOSPHEARE
        
        SOLIDIFIED LAVA FORMS THE VOLCANIC BUILDING
        
        characterized by the crater, volcanic cone, volcanic chimney, magma chamber
        
        VOLCANO ARE DIVIDED INTO
        
        CENTRAL
        
        MOST COMMON TYPE , MAGMA RISES INTO THE EARTH SURFACE FROM THE VOLCANIC CHIMNEY
        
        LINEAR
        
        MAGMA RISES FROM ERUPTIVE FISSURES , SITUATED IN CORRESPONDANCE OF OCEANIC DORSALS ICELAND
        
        DEPENDING ON WHERE MAGMA RISES FROM
- - - - ALONG THE OCEAN RIDGES (LINEAR VOLCANOES ON THE OCEAN FLOOR)
      - ALONG CONTINENTS MARGINS
      - ALONG SOME ARCHES OF ISNALDS
      - WE CAN ALSO FIND VOLCANOES IN ISOLATED AREAS
        
        THEY CAN BE BOTH WHITIN THE CONTINENTS AND IN THE MIDDLE OF THE OCEAN ABYSSAL PLAINS
        
        HOT SPOTS
