Types of Volcanoes Quiz

Kinds of Volcanoes

1. Shield Volcanoes

   • Broad, gently sloping sides.
   • Built up by the eruption of low-viscosity basalt lava that can flow over great distances.
   • Example: Mauna Loa, Hawaii.

2. Stratovolcanoes (Composite Volcanoes)

   • Steep, conical shape with layers of lava, ash, and volcanic rock.
   • Eruptions are often explosive, with viscous lava that doesn't flow far.
   • Example: Mount St. Helens, USA.

3. Cinder Cone Volcanoes

   • Smallest type of volcano, steep slopes made from volcanic debris.
   • Formed from the accumulation of cinders and ash around a single vent.
   • Eruptions are usually short-lived and mildly explosive.
   • Example: Paricutin, Mexico.

4. Lava Domes

   • Formed by the slow extrusion of highly viscous lava.
   • Often found within the craters of larger volcanoes.
   • Can collapse or explode due to pressure buildup.
   • Example: Novarupta Lava Dome, Alaska.

5. Fissure Volcanoes

   • Eruptions occur along cracks in the Earth's surface rather than a single volcanic vent.
   • Typically produce large volumes of basaltic lava that form extensive plateaus.
   • Example: Iceland’s Laki fissure eruption.

6. Submarine Volcanoes

   • Located underwater, often forming island chains as they erupt and build up.
   • Can lead to the formation of new islands (e.g., Loihi, Hawaii).
   • Eruptions can be explosive, producing steam and ash.

7. Supervolcanoes

   • Capable of producing extremely large and explosive eruptions.
   • Often characterized by calderas formed from collapsed magma chambers.
   • Example: Yellowstone Caldera, USA.

Types of Volcanoes

• Shield Volcanoes

  • Characterized by broad, gently sloping sides.
  • Eruptions feature low-viscosity basalt lava that flows over long distances.
  • Notable example includes Mauna Loa in Hawaii.

• Stratovolcanoes (Composite Volcanoes)

  • Have a steep conical shape and are composed of alternating layers of lava, ash, and volcanic rocks.
  • Eruptions tend to be explosive due to the high viscosity of the lava.
  • A well-known example is Mount St. Helens in the USA.

• Cinder Cone Volcanoes

  • Represent the smallest type of volcano, with steep slopes formed from volcanic debris.
  • Created by the accumulation of cinders and ash around a single vent.
  • Eruptions are usually short-lived and mildly explosive, such as the eruption of Paricutin in Mexico.

• Lava Domes

  • Formed by the slow extrusion of highly viscous lava.
  • Typically found within the craters of larger volcanoes.
  • Can experience collapse or explosive eruptions due to pressure buildup; example: Novarupta Lava Dome in Alaska.

• Fissure Volcanoes

  • Eruptions occur along cracks in the Earth's surface rather than from a singular volcanic vent.
  • These volcanoes produce large volumes of basaltic lava, resulting in extensive plateaus.
  • An example is the Laki fissure eruption in Iceland.

• Submarine Volcanoes

  • Situated underwater, often contributing to the formation of island chains during eruptions.
  • Can lead to the emergence of new islands, as seen with Loihi in Hawaii.
  • Eruptions may be explosive, often resulting in the creation of steam and ash.

• Supervolcanoes

  • Capable of generating extremely large and explosive eruptions with far-reaching effects.
  • Distinguished by the presence of calderas formed from collapsed magma chambers.
  • Yellowstone Caldera in the USA is a prominent example.
