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.
