Answers
1
What landform is created when two continental plates collide?
ocean basin
volcano
canyon
mountain range (non-volcanic)
2
Where do earthquakes mostly occur?
where bubbles of magma rise to the surface
when cooling of the mantle occurs
at transform boundaries
when heat causes the mantle to expand
3
Why would this mountain near a tectonic plate boundary continue to increase in elevation?
transform faulting of tectonic plates
colliding of continental plates
seafloor spreading of oceanic plates
subduction of a tectonic plate
4
A boundary where two plates come together, or collide, is called a
divergent boundary.
transfer boundary.
transform boundary.
convergent boundary.
5
Which two plates created the Himalaya Mountains?
Nazca and South American
North American and South American
African and Eurasian
Indo-Australian and Eurasian
6
When two tectonic plates slip or slide past one another, what type of boundary is it called?
transform
convergent
divergent
state
7
Name tectonic plate number 11 on the following map...
Antarctic
Australian
Eurasian
Pacific
8
Which mountains were created when two continental plates collided?
Rockies
Cascades
Andes
Himalayas
9
Which describes the relationship between earthquakes and volcanoes?
Earthquakes and volcanoes are not related in any way.
Volcanic eruptions usually cause severe earthquakes.
Earthquakes & volcanoes often are located where plates meet.
Earthquakes usually cause volcanoes to erupt.
10
How does magma affect the ocean floor?
It has made the Atlantic waters warmer than the Pacific.
It has produced a flat, smooth ocean floor.
It has created a long mountain range on the spreading ocean floor.
It has produced volcanoes along the edges of continents.
11
In the diagram, which event occured at line XY?
erosion
faulting
sedimentary deposition
volcanic eruption
12
Name tectonic plate number 10 on the following map...
African
Arabian
Nazca
Indian
13
What two plates does the San Andreas Fault sit on
Nazca & Eurasian
Pacific & N. American
Atlantic & N. American
Australian & Pacific
14
The theory of plate tectonics attempts to explain the
layering of sedimentary rock.
composition of Earth's inner regions.
movement of Earth's plates.
gravitational forces of Earth.
15
This is a diagram of the mid-ocean ridge. What is causing the ridge to spread apart?
two tectonic plates crashing into each other
one tectonic plate being pushed under another
two tectonic plates moving away from each other
two tectonic plates moving alongside each other
16
Which explains why identical rock types and fossils are found on different continents?
The same forces erode mountains in different locations.
Some rock types are common and found everywhere.
These continents were once joined together.
Organisms swam across the sea.
17
What kind of plate boundary is responsible for the Andes Mountains?
The Nazca plate is converging with the South American plate.
The North American plate is diverging with the South American plate.
The North American plate is converging with the Indo-Australian plate
The Nazca plate and the North American plate are at a transform boundary.
18
Earthquakes can happen far off the coast. What can also happen with this type of earthquake?
volcano
tsunami
global warming
thunderstorm
19
What kind of boundary creates a mid-ocean ridge?
convergent
subduction
divergent
transform
20
The crustal plates of Earth move due to being dragged along by
the rotation of Earth on its axis.
convection currents in the asthenosphere.
the high tides of the oceans.
prevailing winds in the jet stream.
21
Name tectonic plate number 2 on the following map...
Indian
Atlantic
Eurasian
Pacific
22
Why do most earthquakes and volcanos occur in areas of the Pacific Ocean called Ring of Fire?
The ocean water forces the magma to the surface.
A lot of people live in this area.
Colliding lithospheric plate boundaries are found in that area.
That area of the earth is the hottest.
23
Name tectonic plate number 3 on the following map...
S. American
Pacific
Nazca
Eurasian
24
What theory explains the change in the position of the continents during Earth's history?
rock cycle
plate tectonics
natural selection
big bang

African
Eurasian
Arabian
Pacific
26
How is the movement of the two continents shown best explained?
plate tectonics
coastal flooding
volcanic eruptions
magnetic changes
27

Non-volcanic mountains
rift valleys
trenches and volcanic mountains
29

volcanoes
earthquakes
mountains
tsunamis
30
Name tectonic plate number 4 on the following map...
N. American

African
S. American
31
An earthquake is caused by sudden shifts in which of the following layers of Earth?
