Volcanic Domes Quiz

Match the following volcanic feature with its description:

Lava Domes (Volcanic Domes) = Result from the slow extrusion of highly viscous lava Calderas = Large, basin-shaped volcanic depressions formed by the collapse of a volcano after a massive eruption or the emptying of a magma chamber

Match the following volcanic feature with its example location:

Lava Domes (Volcanic Domes) = Lassen Peak in Lassen Volcanic National Park Calderas = Novarupta Dome (Alaska)

Match the following volcanic feature with its eruption characteristics:

Lava Domes (Volcanic Domes) = Can lead to explosive eruptions Calderas = Form during eruptions of silicic magmas that emit large-volume ash-flow tuffs and form Ultra-Plinian eruptive columns

Match the following volcanic feature with its association with composite volcanoes:

Lava Domes (Volcanic Domes) = Occur in the summit craters of composite volcanoes such as at Redoubt Volcanoes in Lake Clark National Park Calderas = Associated with a post-caldera eruptive phase Signup and view all the answers

Match the following volcanic features with their descriptions:

Nonexplosive calderas = Form on the summit of shield volcanoes during large eruptions Submarine Volcanoes = Volcanoes located underwater Fissure Vents = Long cracks in the Earth's surface from which lava erupts Maars and tuff = Low-standing volcanoes with wide, bowl-shaped craters Signup and view all the answers

Match the following volcanic features with their examples:

Yellowstone Caldera = Nonexplosive calderas Axial Seamount = Submarine Volcanoes The Laki fissure = Fissure Vents Diatremes = Maars and tuff Signup and view all the answers

Match the following volcanic features with their characteristics:

Can form seamounts or emerge as islands = Submarine Volcanoes Eruptions often non-explosive, resulting in extensive lava plateaus = Fissure Vents Low-standing volcanoes with shallowly-dipping deposits of tuff = Maars and tuff Funnel-shaped breccia pipes formed via phreatomagmatic explosions = Diatremes Signup and view all the answers

Match the following volcanic features with their associated phenomena:

May contain lakes in their craters = Maars and tuff Dry tuff ring craters = Maars and tuff Eruptions occurring along elongated fissures = Fissure Vents Topographic lows frequently containing lakes = Maars and tuff Signup and view all the answers
