1
During subduction, one tectonic plate is forced below another. The subducting plate is forced into the
mantle
asthenosphere
outer core
inner core
2
The theory of plate tectonics revolutionized scientific thought because it
explained the mineral differences between continents.
mapped the pattern and frequency of earthquakes.
explained the movement of oceanic and continental crusts.
demonstrated how tidal forces affect coastlines.
3
Based on the diagram, which feature is most likely being developed?
An oceanic trench, because one plate is subducting beneath the other.
A mountain range, because both of these continental plates are converging.
A transform fault, because the plates are both moving sideways.
A mid-ocean ridge, because a mountain range forms as the plates separate.
4
Which diagram shows the relative direction of tectonic plate movement that most commonly forms mountain ranges?
c
a
d
b
5
Which
best
explains how the Appalachian Mountains formed?
An earthquake folded the land.
Tectonic plates pulled apart.
tectonic plates collided.
An ancient river flooded.
6
The movement of tectonic plates should be described as a
predictable process.
quick process.
slow, continuous process
an increase in crust movement over time.
7
Mountains are most likely formed
along tectonic plates.
when land sinks.
from earthquakes.
when glaciers melt.
8
Which of these is the result of subduction at deep ocean trenches around the Pacific plate?
Rift valleys
Plateaus
Faults
Volcanoes
9
How does this diagram help confirm Alfred Wegener’s hypothesis of continental drift?
It demonstrates that Earth’s crust is the thinnest of its layers.
It shows that Earth’s mantle has several concentric layers.
It shows how crustal plates float on convection currents in the mantle.
It models how Earth’s core is divided into an inner core and an outer core.
10
The Hawaiian islands are located in the middle of a tectonic plate and are the direct result of the plate
colliding with another tectonic plate and being forced upward.
applying great pressure on the crust causing constant earthquakes.
being forced under another tectonic plate at a subduction zone.
moving over a hot spot where magma breaks through the crust.
11
Which process must occur in the mantle to make tectonic plates move?
convection currents
seafloor spreading
igneous intrusions
normal faulting
12
Select all of the features that can form as a result of tectonic plates diverging.
trench, mountains, ocean basin, mid-ocean ridge
trench, rift valley, mountains, ocean basin
trench, rift valley, ocean basin, mid-ocean ridge
rift valley, mountains, ocean basin, mid-ocean ridge
13
Why were
Glossopteris
fossils found on 4 different continents if their seeds couldn't disperse by wind?
Glossopteris was versatile enough to adapt to all climates.
The landmasses were joined together in prehistoric times.
The northern climate regions were not suitable for plant growth.
Fossils were much better preserved in the southern continents.
14
Which of these formed on the Asian continent by two continental plates that have been colliding for millions of years?
A tall mountain chain
An uneven thickness of sedimentary layers
Large fields of gravel
Large freshwater lakes linked by rivers
15
Which discovery provided the explanation for how continental drift happens?
Tsunamis
Seafloor spreading
Earthquakes
Igneous rocks
16
Which piece of evidence supports plate tectonic theory?
The weathering and erosion of coastlines
New crust formed by seafloor spreading
Plant fossils that are similar in size
Rocks with different physical appearances
17
The illustration shows how most of the recycling of rock from Earth’s crust occurs. What is this process called?
Convergence
Subduction
faulting
Divergence
18
Which feature results when plates of different densities converge and one plate slips under the other?
A ridge
A rift zone
A fault
A trench
19
Fossils of cold-blooded animals have been found in bitterly cold Antarctica. Which explains how they survived there?
The plate on which Antarctica rests was once closer to the equator.
Cold-blooded animals were adapted to the cold.
Cold-blooded animals would migrate to cold places in the summer.
Ancient humans living in Antarctica domesticated a variety of organisms.
20
Which diagram accurately shows how Earth's internal energy causes movement of semi-solid materials within Earth?
c
a
b
d
21
Which of these tectonic plate boundaries is
most
likely to form a volcano?
An oceanic plate sliding past a continental plate
A continental plate colliding with a continental plate.
An oceanic plate colliding into a continental plate.
A continental plate sliding past a continental plate.
22
Which model best explains plate movement?
d
b
a
c
23
Which of these correctly identifies plates 3 & 6 from the map?
3: Nazca, 6: South American
3: North America, 6: Eurasion
3: Indo-Australian, 6: African
3: Indo-Australian, 6: South American
24
Which geologic structure will
most
likely take the longest time to form?
A fault
a river meander
A sinkhole
A mountain range
25
What is the best explanation for how 200-million-year-old
Mesosaurus
fossils were found on both S. America and Africa?
Ancient organisms were able to swim much farther than modern organisms.
Modern land masses were once connected but moved apart.
The same environmental conditions existed all over Earth.
The same organisms existed more than once in the history of Earth.
