How Stratovolcanoes Form and Erupt - Geological Process Explained #1810299 (License: Personal Use)

The left panel shows a stratovolcano forming through successive eruptions that deposit layers of lava, creating its classic steep, conical shape; molten rock (magma) rises from deep within the Earth into the upper crust. The right panel depicts the eruption phase, where dissolved gases in the magma expand as pressure builds, ultimately causing a violent explosive eruption that ejects ash, rock, and pyroclastic material.

Used in educational geology content, science textbooks, or museum exhibits to explain volcanic mechanics; matches user intent for understanding volcano types, eruption triggers, and earth science fundamentals.
