Parts of a Volcano:
Central Vent: Opening from which lava flows
Magma Chamber: source of molten materials that flow to surface during eruption
Conduit/Fissure: Connects vent to magma reservoir
Caldera: bowl-like depression at the top of a volcano, can be created either by collapse caused by empty magma reservoir or by volcano blowing its top off
Types of Eruptions:
Hawaiian: Lava Streams
Strombolian: Huge clots of molten lava burst from summit crater to form luminous arcs through sky
Vulcanian: Dense cloud of ash-laden gas explodes and rises above peak
Plinian: most powerful eruption, explosive ejection of viscous lava, ash and gas travel tens of miles into air (featured in picture)
