volcanoes
calderas
the greatest volume of volcanic material is produced by
eruptions of cinder cones
eruptions of composite cones
eruptions along ocean ridges
eruptions of shield volcanoes
the most explosive type of volcanic activity is associated with
cinder cone
sills
composite cones
shield volanoes
a magma's viscosity is directly related to its
depth
age
color
silica content
what are the pulverized rock, lava, ash, and other fragments ejected from the vent of a volcano called?
sills
craters
pahoehoes
pyroclastic material
which type of volcano consists of layers of lava flows and pyroclastic material?
composite cone
cinder cone
shield volcano
laccolith
the hotter of two types of basaltic lava commonly forms
aa flows
pyroclastic flows
pahoehoe flows
lapilli flows
what is the very large depression at the top of some volcanoes called?
a vent
a lava plateau
a volcanic neck
a caldera
when silica-rich magma is extruded, ash, hot gases, and larger fragments propelled from the vent at high speeds may produce which of the following?
a lava plateau
a lahar
a pahoehoe flow
a pyroclastic flow
what feature may form in an intraplate area over a rising plume of hot mantle material?
a hot spot
a dike
a subduction zone
an ocean ridge
what is a volcanic neck, and how does it form?
it is the material that hardens from pyroclastic material pooling in one spot
it s a rock that forms on the side of a volcano that forms a neck and spews out lava
the neck is the rock in a volcanic pipe that is more resistant to erosion and remains standing after the surrounding cone has been eroded
what is the ring of fire
name for volcanoes located around the margins of the Atlantic ocean
name for volcanoes located around the margins of the Pacific ocean
name for the volcanoes located around the margins of Hawaii
The Hawaiian Islands and Yellowstone National Park are associated with which of the three types of volcanism?
Hot Spot
Caldera
Intraplate volcanism
continental island arcs
what is the chain of volcanoes called that forms at a convergent boundary between a subducting oceanic plate and a continental plate? What type of volcano commonly forms?
a continental volcanic arc; shield cone
a continental volcanic arc; cinder cone
a continental volcanic arc; composite cone
how are pyroclastic materials classified?
size and shape
weight and force
lava and magma
