Volcanoes are mighty mountains

September 29, 2026

Volcanoes are evidence of the remarkable journey of molten rock, which begins miles (kilometers) beneath our feet. What happens on magma’s ascent determines whether it erupts explosively (like Mount St. Helens on May 18, 1980), oozes lava (like Mount St. Helens during its 2004–2008 dome-building event), or cools and crystallizes underground, never to erupt at all.

This two-page educational activity uses a conceptual model of a stratovolcano to connect volcanic processes with personal growth. On page 1, students explore how magma is generated and moves through the crust to form a volcano, using core concepts we can relate to: strengths, support, challenges, motivations, and goals. On page 2, students reflect on their own journeys to draw parallels between what happens at volcanoes and how personal motivations and challenges shape them, just as magma shapes volcanoes, and volcanoes transform landscapes.
