Answers
1
which of the following is not part of a pluton?
laccolith
dike
caldera
batholith
2
which type of stress causes a reverse fault
torsional
compression
shear
tension
3
which of the following increases in thickness of lava and explosiveness of eruption
basaltic, andesitic, rhyolitic
cinder, composite, shield
rhyolitic, basaltic, andesitic
basaltic, rhyolitic, andesitic
4
which way does a divergent plate boundary move
apart
up and down
together, colliding
north and south
5
which waves stopped at the outer core
secondary
earthquake
tsunami
primary
6
Which seismic wave shakes side-to-side (squeeze and pull)
surface
primary
reductive
secondary
7
how many seismometers are needed to find an epicenter
3
4
2
1
8
why are there volcanoes in Hawaii and Yellowstone
llamas
plate boundaries
faults
hot spots
9
which area has a high risk for earthquakes
Missouri
Pennsylvania
North Dakota
North Carolina
10
what does the travel-time curve help us do
find distance to epicenter
prove the outer core is liquid
find depth of focus
see the type of waves that hit an area
11
What is the hole at the top of a volcano called
crater
tephra
batholith
vent
12
what does the principle of original horizontality tell us
layers should be flat
magma intrusions are younger than layers it cuts through
oldest on the bottom, youngest on top
uneven layers were changed after they were laid down
13
when was the year without a summer
1940s
640,000 ya
1816
1961
14
Why does our area have earthquakes?
Ridge push distorting the crust
Isostatic rebound
Divergent plate boundary in Atlantic
Small fault near Somerset
15
Which magma would most likely found in areas near subduction zones?
rhyolitic
andesitic
pahoehoe
basaltic
16
which type of lava would result from a lot of melting of continental crust
andesitic
basaltic
composite
rhyolitic
17
what would you expect from a magnitude 5 quake
minor shaking, some people don't notice it
buildings collapse, ground cracks
major damage to structures and ground level changes
moderate shaking, some damage
18
Which type of volcano forms at subduction zones
basaltic
cinder
composite
shield
19
which type of stress pulls apart
shear
tension
compression
surface
20
s-wave movement
east and west
up and down
circular
side-to-side
21
which type of volcano would Hawaii have
Hawaiian
rhyolitic
basaltic
andesitic
22
Which of the following means rocks broke and crust moved
stress
viscosity
convection
strain
23
Why is Mt.Vesuvius famous?
the only shield volcano in Europe
huge pyroclastic flows
it is a huge cinder cone
it is nearly constantly erupting
24
what does the travel-time curve give us?
strength of seismic waves
types of seismic waves
none of these
speeds of seismic waves
25
which mineral makes magma thicker
magnesium
silica
iron
rhyolite
26
which fault would result from shear stress
reverse
strike-slip
normal
composite
27
what caused the year without a summer
cold air from northern latitudes shifting southward and disrupting climate
tsunamis
Ben Franklin
ash and gas blocking sun
28
What causes plate tectonics
Earthquakes in crust
Plates moving
Convection in mantle
Mountains and weight
29
p-wave movement
north and south
circular
side-to-side
up and down
30
which plate boundary usually creates a volcano
convergent
tensional
strike-slip
transform
31
which way does a normal fault move
upwards
together, colliding
north and south
apart
32
What is superposition
Magma cutting through is younger
Youngest rocks on the bottom
Oldest rocks on bottom
Layers should be flat
33
what is viscosity
type of stress at a fault
strength of earthquake
thickness of lava
speed of earthquake waves
34
Which of the following seismic waves gave us evidence about the outer core's composition
p
focus
surface
s
35
where would pancaking most likely occur
areas near water/wet soils
multi-story buildings
near shield volcanoes only
under a laccolith
36
what is a pyroclastic flow
convection currents in mantle
basaltic lava flowing down the side of volcano
hot ash and gas rushing down volcano
thin and runny lava
37
Hawaii and Yellowstone have volcanic activity for the same reason. That reason is…
Continental-continental boundary collisions
They sit above subduction zones
A chimney of magma poking holes through crust
Divergent boundaries pulling apart and erupting lava
38
What does pressure do to the melting temperature of rocks and minerals?
decreases melting temperature
Upward convection
Downward convection
Increases melting temperature
39
what is a focus
where a laccothith forms
where some rocks broke
an unconformity
the vent of a volcano
40
