1
What kind of rock fold describes where the oldest rock layers are located in the fold's center?
asymmetrical fold
syncline
symmetrical fold
anticline
2
Which of the following is a process that occurs at a divergent plate boundary?
subduction of oceanic crust
continental collisions
formation of oceanic crust
formation of continental crust
3
Why do the dots on map tend to form a long curving line along western edge of Pacific Ocean?
pressure on sea floor due to weight of water
This part of ocean has high rate of hurricanes and typhoons
This part of ocean is directly above tectonic boundaries
Increase in tsunamis led to increase in earthquakes
4
Which geological event is caused by movement of tectonic plates?
tides
eclipse
thunderstorm
earthquake
5
Which of the following land features is caused by the movement of tectonic plates?
glacier
sinkhole
mountain
river
6
Which volcanic feature forms a relatively small depression around a volcano's vent?
crater
caldera
lava plateau
fissure
7
What is the primary way in which folded mountains form?
tension
shear stress
volcanic activity
compression
8
What causes an earthquake to happen?
energy is transferredto rock layers from convection currents
large amounts of rocks suddenly shift downward
rocks along a fault move suddenly and release energy
rocks deform slowly as a result of physical stress
9
Which of the following statements accurately describes Pangaea?
a block of lithosphere that moves on top of asthenosphere
hypothesis behind continental drift
a single large continent that formed in Earth's past
single, large ocean that formed in Earth's past
10
Vents are long cracks in the ground. What type of crack is the earth's surface called?
fissure
caldera
lava plateau
crater
11
Which statement below accurately describes a tectonic plate?
structural layer of earth, including crust and mantle
a continent or ocean
block of lithosphere that moves around on top asthenosphere
outermost compositional layer of earth
12
Which type of volcano is made mostly of pyroclastic materials?
shield volcano
stratovolcano
composite volcano
cinder cone
13
What type of motion happens in a normal fault?
hanging wall drops down relative to footwall
walls move side to side past each other horizontally
footwall drops down relative to hanging wall
hanging wall moves up relative to footwall
14
How could tectonic plate motion cause such a deformation?
compression at divergent boundary cause folded mountains
compression at convergent boundary caused fold mountains
tension at divergent boundary caused fault block mountain
tension at convergent boundary caused fault block mountain
15
Which of the following is a process that occurs at divergent plate boundaries?
formation of mid ocean ridges
crust material
magnetic reversals
formation of continental crust
16
What process causes hot, solid rock to rise through the mantle at hot spots?
condensation
radiation
convection
conduction
17
What happens at a tectonic plate boundary?
Hot mantle rises to form volcanoes
two tectonic plates interact with each other
continents get smaller as a result of subduction
An oceanic plate becomes a continental plate
18
What happens when tectonic plates move within the pattern of subduction?
transform boundary occurs
sea floor spreading occurs as oceanic plates move
an ocean forms
volcanic mountain ranges form
19
After molten material flows over and over out of earth's vents, what will form on surface?
magma chamber
volcanic mountain
plate boundary
caldera
20

North American, South American, Pacific, Eurasian
Antarctica, Africa, Europe, Australia, North America
Pacific, Atlantic, Indian, Arctic, Southern
lithosphere, asthenosphere, mesosphere, mantle, crust
