Volcano Vocab

TermDefinition
Characteristics of a Shield Volcano Flatter to the ground with a gradual slope. Formed by thick lava flows that move slowly and are not explosive.
Plate Tectonics The theory that Earth's outer crust is divided into several plates
Characteristics of a Composite Volcano Large symmetrical cones built by alternating layers of lava flows and volcanic ash,that can create explosive eruptions.
Characteristics of a Cinder Cone Volcano Small cones-shaped volcanoes with steep angled sides. Blobs of lava spew into the air during eruptions and fall on the sides of the volcano. Built over a short period of time.
Lava Dome Volcano Lava is too thick to flow a great distance. Lava cools and piles up around the vent.
Secondary Vent Magma can reach the surface in other areas.
Magma Molten rock under the earth's surface.
Lava Molten rock above earth's surface.
Ring of Fire An active volcanic region where many eruptions and earthquakes take place in the pacific ocean.
Hot Spot Magma rises to the crust and breaks through which usually happens in the middle of a tectonic plate.
Magma Chamber Large underground pool of molten rock sitting underneath the earth's crust.
Main Vent The weak point in the Earth's crust where hot magma rises from the magma chamber and reaches the surface.
Crater Circular basin or depression.
Pyroclastic Flow Fast-moving current of hot gas and rock that moves away from a volcano
Caldera A large basin-like depression resulting from the explosion or collapse of the center of a volcano.
Volcanic Neck Where the volcano reaches its peak.
Igneous Intrusion When lava cools and hardens below the surface.
Subduction Zone When crust moves under or over each other.
Volcanic Ash Small pieces of pulverized rock, minerals, and volcanic glass created during eruption.
Volcanic Bomb Large projectiles thrown through the air.
Dormant Volcano Quiet now but might erupt again
Extinct Volcano Unlikely to erupt again but still could
Dike Vertical Intrusions
Sill Horizontal Intrusions
