Volcanic eruptions

The video discusses the Yellowstone Volcano, highlighting its popularity despite being on a massive volcano. It explains how heat from underground creates hot springs and geysers. The video details the process of volcanic eruptions, where heat energy turns solid rock into magma, which then erupts as lava. It also covers the release of gases like water vapor and sulphur dioxide during eruptions. Finally, it describes how volcanic materials cool and solidify, and the volcano remains dormant until the next eruption.
