Volcano Formation and Eruptions

The video explores the fascinating world of volcanoes, detailing their structure and components. It covers the magma chamber, conduit, volcanic cone, and different types of volcanoes like strata and cinder cone. The video also explains fissures, craters, and the eruptive column, emphasizing the role of tectonic plates in volcano formation. A quiz question is posed to engage viewers.
