FranTypes of volcanic vents include central vent, fissure vent, and parasitic vent. Central vents are the main opening from which lava and gases are expelled. Fissure vents are elongated fractures in the Earth's crust from which lava can erupt. Parasitic vents are smaller secondary openings located near the central vent through which additional lava may be emitted.

Does Mt Erebus have secondary vents?
Yes, Mt. Erebus in Antarctica has secondary vents located on its flanks, which are openings in the volcano's surface through which magma, gas, and volcanic ash can erupt. These secondary vents can release pressure from the main crater and contribute to the overall volcanic activity of the mountain.
What kind of organisms live in lava?
Organisms such as extremophiles, specifically thermophiles, are known to live in lava or near volcanic vents. These organisms have adapted to survive in extreme heat and acidic conditions commonly found in volcanic environments. They can include bacteria, archaea, and some specific types of algae and fungi.
What is the name of the rock with angular fragments?
Large angular rock fragments describes an agglomerate. This usually happens in volcanic vents.
Volcanic features that can sometimes be seen above ground?
Some volcanic features that can sometimes be seen above ground include volcanic craters, lava domes, volcanic cones or mountains, and fumaroles (vents emitting volcanic gases). These features result from past or more recent volcanic activity and provide insights into the geological processes that shaped the area.
What is volcanic tuft made from?
Volcanic tuff is a type of rock composed of volcanic ash and other volcanic debris that has been compressed and cemented together over time. It is typically formed during explosive volcanic eruptions and can vary in color and texture depending on the composition of the volcanic materials involved.
