science 3rd quarter volcanoes

• Volcano

  Ano opening in the earth's crust through which molten lava, ash, and gases are elected
• Sheild Volcanoes

  It have a slow slope and consists of frozen lava after it is hardned
• Cinder Cone Volcanoes

  It is consits of mostly loose, gainly cinder and have little to no lava
• Composite Volcano

  It have another name called "Strato Volcanoes"
• Caldera Volcanoes

  Its a circular depressions in the ground over a magma chamber
• Fissure Volcanoes

  Its have no main crater the ground just split and lava pours out through the crack
• Composite volcano

  It consists of lava that is mixed with sand or gravel which turn creates cinders or volcanic ash
• Types of Magma

  Granite magma

  Basalt magma
• Granite Magma

  Consists of light colored rock and is not as hey as basalt magma.
• Basalt Magma

  Consists of dark colored rocks and is much heavier then granite magma
• Granite magma

  It is very sticky and flows rather slowly
• Basalt Magma

  It flows more fluidly then molten granite
• Volcano Environment

  • Island arc environment
  • Oceanic environment
  • Continental environment
• Oceanic Environment

  volcanoes are aligned along the crest of a board ridge that marks an active fracture system in the oceanic crust
• Island Arc Envinronment

  volcanoeslie along the rest of an arcuate
• Continental Environment

  Volcanoes are located unstable, mountainous belt, that have thick roots of granite or granite like rock
• ACTIVE VOLCANO

  These are volcanoes that erupt occasionally
• EXTINCT VOLCANOES

  It has not erupted or no proof of erption in historical times
• inactive/dormant volcano

  These are volcanoes that have no record of eruption
• volcanic domes

  It is a rounded, steep, mound that is formed by small, bulging masses of lava primarily composed of either dacite or rhyolite
• Submarine Volacano

  is created when magma erupts in the underwater fissure of the earth
• Super Volcano

  Described to produce the lowest eruption on earth
• Subglacial Volcano

  It is a volcano in the surface of a glacier or ice sheet which is then melted into a lake
• PLINIAN

  EXCESSIVELY EXPLOSIVE TYPE OF ERUPTION OF GAS AND PYROCLASTIC
• PELEAN

  VERY VIOENT ERUPTION CHARACTERIZED BY VOLMUNOUS EXPLOSIVE EJECTIONS OF PUMICE AND ASH FLOWS
• VULCANIAN

  CHARACTERIZED BY TALL ERUPTION COLUMNS THAT REACH UP TO 20KM HIGH WITH PYROCLASTIC FLOW AND ASHFALL TEPHRA
• STROMBOLIAN

  A PERIODIC WEEK O VIOLENT ERUPTION CHARACTERZED FOUNTAIN LAVA
• PHREATOMAGMATIC

  IS A VIOLENT ERUPTION DUE TO TH CONTACT BETWEEN WATER AND MAGMA THAT LEADS TO A LARGE COLUMN OF VERY FINE ASH
• PHREATIC OR HYDROTHERMAL

  IS A STEAM DRIVEN ERUPTIO AS THE HOT ROCKS COE IN CONTACT WITH WATER
• LAVA

  IS A RED BOT WITH A TEMPERATURE OF MORE THAN 1,1OO C
• ROCK FRAGMENTS

  ARE FORMED FROM STICKY MAGMA WITH TRAPPED GASES
• WIND WARD SIDE: COOL, MOIST
• LEEWARD: WARM,DRY
• LATITUDE

  HORIZONTAL OR INVERTIAL IN GLOBE
• AS LATITUDE INCREASE THE AVERAGE ANNUAL TEMPERATURE DECREASE
• TROPICAL ZONE

  GEION BETWEEN 23,5 NORYH AND 23,5 SOUTH OF THE EARTH EQUATOR
• DRY ACID CLIMATES

  IS CHARACTERIZED BY DEFICIENT AMOUNT OF PRECIPITATION THOUGHOUT THE YEAR
• TEMPERATE ZONE

  REGO BETWEEN 23,5 AND 66,5 NORTH AND SOUTH OF THE EQUATOR
• POLAR ZONE

  THE REGION BEETWEEN 66,5 NORTH AND SOUTH OF THE EQUATOR
• WATER MODERATES THE TEMPERATURE
