1. Magma Chamber: This is the underground reservoir of molten rock (magma) that feeds the volcano.
2. Conducts: These are pathways or channels within the Earth's crust that allow magma to rise from the magma chamber to the surface.
3. Vent: This is the opening on the surface of the Earth where magma erupts.
4. Crater: This is the bowl-shaped depression at the summit of the volcano, formed by the eruption of volcanic material.
5. Cone: This is the conical structure built up by layers of lava, ash, and other volcanic material that erupt from the vent.
Remember, the actual structure of a volcano can be more complex, with additional features like parasitic cones, calderas, and lava flows.
