Volcano

The video tutorial explores volcanoes, starting with their definition as landforms where molten rock erupts through the Earth's surface. It explains the role of plate tectonics in causing volcanic eruptions, particularly in the Pacific Ring of Fire. The video describes different types of volcanoes: composite, shield, and cinder cone, highlighting their characteristics and eruption styles. It also discusses the activity status of volcanoes, categorizing them as active, dormant, or extinct. Additionally, the video mentions volcanoes beyond Earth, such as Olympus Mons on Mars. The tutorial concludes with the ongoing study of volcanoes by scientists known as volcanists.
