  • 1. Ch. 3 Sec. 4 Volcanic Landforms
  • 2. landforms from lava & ash shield volcano cinder cone volcano composite volcano lava plateau caldera
  • 3. shield volcano
    • Quiet eruptions
    • Gently sloping mountain
  • 4. Mauna Loa Earth's Largest Volcano
  • 5. cinder cone volcano
    • explosive eruptions
    • ash, cinders & bombs
    • cone-shaped hill
  • 6.
    • Paricutin in Mexico
  • 7. composite volcano
    • tall cone shaped mount.
    • quiet eruptions (lava) alternate w/ explosive eruptions (ash)
  • 8.  
  • 9. lava plateau
    • layers of thin, runny lava build up high level area
  • 10. caldera
    • huge hole left by collapse of volcanic mount.
  • 11. soils from lava & ash
    • fertile (rich) soil
    • plants grow well
  • 12. Landforms From magma Volcanic neck dike sill batholith Dome mountain
  • 13. Volcanic neck
    • When magma hardens in volcano’s pipe
  • 14. dike
    • Magma that forces itself across rock layers
  • 15. sill
    • magma squeezes between horizontal layers of rock
  • 16. batholith
    • large mass of rock forms when magma cools in crust
  • 17. Dome mountain
    • hardened magma
    • forms when uplift pushes batholith toward surface
  • 18. geothermal activity hot springs geyser geothermal energy
  • 19. hot springs
    • formed when groundwater is heated by nearby body of magma or hot rock underground
  • 20.  
  • 21. geyser
    • Fountain of water & steam that erupts from ground
  • 22. geothermal energy
    • water heated by underground source  creates steam  energy
  • 23.
    • What is this volcano made of? How do geologists classify a volcano made of these materials?           
    • What is the feature labeled A in the diagram? What is the feature labeled B? How do these features form?           
    • What is the feature labeled C in the diagram? If this feature becomes plugged with hardened magma, what could happen to the volcano? Explain.           
    • What is the feature labeled D in the diagram? What can you infer about this feature if the volcano becomes dormant?
