This video explores the fascinating world of volcanoes, explaining why only some are active while others remain dormant or extinct. It covers key concepts such as different types of volcanoes, locations of active volcanoes near plate boundaries, and the formation of islands from hot spots, with a focus on Japan and the Hawaiian Islands. The video also distinguishes between dormant volcanoes—those that have erupted in recorded history but not recently—and extinct volcanoes, which have no recorded eruptions.
