The volcano model depicts a cross-section of a stratovolcano, or stratovolcano, showing its internal and external structure.

Main elements of the model:

Magma chamber: The area under the volcano in the Earth's crust where magma accumulates.

Flue: The central vertical channel along which magma moves toward the surface.

Crater: The funnel-shaped depression at the top of a volcano from which lava, ash, and gases erupt.

Layered structure: The cone of a volcano consists of alternating layers of petrified lava flows and volcanic ash and other tephra.

Side vents and sills: Side channels branching off from the main vent and magma (sills) that have penetrated between the layers.
