  • An explosive type of volcano, a large, nearly perfect sloped volcano.
    Stratovolcano
  • A type of volcano considered the gentle giant because it is broad, non-explosive, and similar to a warrior's shield.
    Shield Volcano
  • A volcano that is currently erupting, or has the potential to erupt in the future.
    Active Volcano
  • A non-explosive, small, and the simplest type of volcano.
    Cinder Cone Volcano
  • A type of explosive eruption characterized by a relatively mild blast of magma.
    Strombolian Eruption
  • Which layer of the Earth is liquid?
    Outer Core
  • It is the most explosive type of eruption.
    Plinian Eruption
  • Which process involves one tectonic plate sinking beneath another?
    Subduction
  • Which type of crust is constantly built and destroyed by geological processes?
    Oceanic Crust
  • Which layer of the Earth is solid and under immense pressure?
    Inner Core
  • It is a natural opening in the Earth’s surface where magma, gases, and ash escape from beneath the surface.
    Volcano
  • What type of crust is less dense?
    Continental Crust
  • It is a type of explosive eruption characterized as deadly due to fast-moving hot gas and debris.
    Pelean Eruption
  • What type of crust is mostly composed of granitic rocks?
    Continental Crust
  • What type of crust is mostly composed of basaltic rocks?
    Oceanic Crust
  • Underground reservoir where molten rock (magma) accumulates before an eruption.
    Magma Chamber
  • A volcano that has not erupted for a long time and shows no signs of future activity.
    Inactive Volcano
  • A passageway that connects the magma chamber to the vent, allowing magma to travel upward.
    Conduit
  • Which hemisphere is dominated by water?
    Southern Hemisphere
  • It is typically a non-explosive and relatively gentle type of eruption.
    Icelandic Eruption
  • It is the weakest and calmest type of eruption.
    Hawaiian Eruption
  • It is characterized by an explosion filled with ash that reaches up above the peak.
    Vulcanian Eruption
  • Openings that emit steam and gases like sulfur dioxide, often found near the crater.
    Fumarole
  • It is a bowl-shaped depression at the top of the volcano, formed by eruptive activity.
    Crater
  • Which layer of the Earth is the thickest?
    Mantle
