Erupciones volcánicas

The video explains the process of volcanic activity, focusing on the Yellowstone volcano. It describes how underground heat creates hot springs and geysers, and how thermal energy transforms solid rock into magma. The magma rises to the surface, causing eruptions that release lava and gases like water vapor, carbon dioxide, and sulfur dioxide. Over time, volcanic materials cool and solidify, and the cycle repeats with the next eruption.
