Studied by 6 peoplecollision plate boundary
a convergent plate boundary which lacks oceanic crust
convergent plate boundary
where a denser oceanic plate is subducted under a continental crust
transform fault plate boundary
a fault along a plate boundary where the motion is predominantly horizontal
divergent plate boundary
where new crust is generated where plates pull apart and magma rises due to convection currents
shield volcano
a volcano shaped like a bowl in the middle with long gentle slopes made by basaltic low-viscosity lava
cinder volcano
a volcano with a conical shape and a cratered summit with steep sides formed by the accumulation of fragments of volcanic rock
composite volcano
a volcano with steep symmetrical profiles formed from multiple layers of hardened lava and volcanic ash
lava dome volcano
a volcano shaped as a steep-sided mound formed when erupting lava is too thick builds up by slow eruptions over time
Icelandic eruption
effusions of molten basaltic flow from fissures
Hawaiian eruption
fluid lava flows from summit and radial fissures
Strombolian eruption
bursts of expanding gases ejecting lava clots
Vulcanian eruption
moderate gas explosions which are laden with volcanic ash
Pelean eruption
outbursts generating pyroclastic flows and volcanic gas
Plinian eruption
gases boiling out of gas-rich magma which generate enormous and continuous jetting blasts that core out the magma conduit
