TED-Ed: What makes volcanoes erupt? | Steven Anderson

The video explores the formation and eruption of the volcano Poku Teen, detailing how magma forms and remains beneath the Earth's surface due to geological factors. It discusses causes of eruptions, including increased magma pressure and natural processes like magma cooling. The video also covers how unloading and erosion can trigger eruptions, and how rock layers weaken due to tectonic activity. Finally, it highlights the challenges in predicting eruptions and the technologies used to study them.

What geological factors contribute to the formation of magma?
