Volcano Anatomy: Labeled Diagram Explaining Key Geological Features #168213 (License: Personal Use)

This educational illustration depicts a stratovolcano in eruption, showcasing subsurface magma pathways (dykes and sills), the central magma chamber, and surface features like the crater, vent, and parasitic cone. Molten lava flows down the flanks while steam, gas, and ash erupt from the summit, and layered pyroclastic deposits form the volcano’s outer slopes. The diagram emphasizes how magma migrates through fractures and chambers before reaching the surface.

Used in earth science education, geology textbooks, museum exhibits, and online learning platforms to teach volcanic structure and eruption mechanics; matches user intent for academic study or科普 curiosity about how volcanoes work.
