Cinder cones
Tastatur-Befehle:
= drehen,
= vor-/rückwärts,
= scrollen
- built from loose material (particles) -> solidify and falls
- round, flat, bowl-shaped crater
- at destructive zones
Stratovolcanoe
Tastatur-Befehle:
= drehen,
= vor-/rückwärts,
= scrollen
- built from alternating lava layers, lava flows through vent or fissures
- steep-sided, symmetrical, snow on top
- at destructive zones
Shield volcano
Tastatur-Befehle:
= drehen,
= vor-/rückwärts,
= scrollen
- built from highly fluid lava -> widely spread
- at constructive zones
Lava Domes
Tastatur-Befehle:
= drehen,
= vor-/rückwärts,
= scrollen
- built from viscous lava (bulbous), dome grows by expension from within
- at constructive zones
Calderas
Tastatur-Befehle:
= drehen,
= vor-/rückwärts,
= scrollen
- magma chamber is emptied in one eruption -> collapses down -> secondary vents from within the crater
- most at constructive zones, sometimes destructive
Maar
Tastatur-Befehle:
= drehen,
= vor-/rückwärts,
= scrollen
- built from explosions caused by groundwater coming into contact with hot magma
- crater filled with water
- at destructive zones
Hawaiian Eruption
Tastatur-Befehle:
= drehen,
= vor-/rückwärts,
= scrollen
- fluid, mafic lava
- fountaining and lava flows
- constructive margins
-> Kilauea
Strombolian Eruption
Tastatur-Befehle:
= drehen,
= vor-/rückwärts,
= scrollen
- every few minutes
- explotion of lava due to escaping gas bubbles
- destructive margins
Surtseyan Eruption
Tastatur-Befehle:
= drehen,
= vor-/rückwärts,
= scrollen
- mostly mafic
- magma interacts explosive with water
- undersea volcano
- destructive margins
Vulcanian Eruption
Tastatur-Befehle:
= drehen,
= vor-/rückwärts,
= scrollen
- short, violent, small explotion of viscous magma
- tephra, ash clouds, pyroclastic demsity currents
- destructive margines
Plinian Eruption
- very viscous lava
- eruption columns of gas and ash
- falls of ashes, scoria, lava bombs, pyroclastic density currents
- destructive margins
