Study Notes
Volcano Components
-
Magma Chamber: Large underground reservoir of liquid rock; a source for volcanic eruptions.
-
Crater: Bowl-shaped depression located at the summit of a volcano, formed as a result of explosive eruptions.
-
Pipe: Vertical channel through which magma travels to the surface; fills with solidified magma over time.
Lava and Eruption Products
-
Lava Layers: Formed when flowing lava cools and solidifies into igneous rock; layers build up over successive eruptions.
-
Lava Flow: Molten rock that moves fluidly from an erupting vent; crucial for understanding volcanic behavior and hazards.
-
Ash Cloud: Composed of tiny particles from explosive eruptions; can disrupt air travel and affect weather patterns.
Volcanic Openings
-
Side Vent: Secondary openings on the volcano's flanks; release lava, gases, and pyroclastic materials during eruptions.
-
Vent: Main opening on the surface of a volcano; directly linked to magma source, allows for the emission of volcanic materials.
