The term 'Volcano Features' can refer to a variety of features associated with volcanoes, such as VENTS. VENTS are openings in the Earth's surface that allow molten rock, ash, and gases to escape from a volcano. They are typically found near the summit of a volcano, and can be either explosive or effusive. Explosive VENTS are characterized by violent eruptions, while effusive VENTS are characterized by slow, steady lava flows.
