1
What type of
landform
is created when 2 plates are moving away from each other?
volcanoes
fault
mountains
mid-ocean ridges
2
A continental plate collides with an oceanic plate, which plate is
subducted
?
continental plate
oceanic plate
3
Where is the oldest crust found on the ocean floor?
where ever a volcano is erupting
furthest away from the mid-ocean ridge & close to a landmass
next to the mid-ocean ridge
where two plates are converging
4
What letter would you choose to represent where the newest crust is formed?
B
A
5
What type of landform is created when 2 plates are
converging
?
mountains
valleys
mid ocean ridges
fault
6
What causes the
tectonic plates
to move?
the inner core and outer core
volcanoes
earthquakes
convection currents
7
What type of
event
is created when two plates are sliding past each other?
mid ocean ridges
mountains
volcanoes
earthquakes
8
What type of plate boundary is shown in the picture?
divergent
convergent
transform
9
If an oceanic plate is being subducted under a continental plate, what landform will form?
mountain range
mid-ocean ridge
islands
deep ocean trench
10
What is the theory of plate tectonics?
Earth’s outer layer is broken up into moving tectonic plates.
Oceanic plates are denser than continental plates
one plate is subducted under another plate
two plates are converging
11
What do we call the process when two oceanic plates
diverge
and
new crust
is formed?
mountains
sea-floor spreading
earthquakes
oceanic - oceanic
12
How do scientists know if a
tectonic plate
has moved?
they measure the plates every day
they use maps of the stars
they have drilled into the plates
they use GPS

volcanic eruptions
earthquake
The Core
tsunamis
16
What type of plate boundary is shown in the picture?
transform
divergent
convergent
17
Which is
not
evidence Wegener used for this theory of Continental Drift?
land forms found of different continents
fossils found on different continents
continents fit together like a puzzle
oceans matched up
18
Where is the newest crust located on the ocean floor?
crust closest to the mid-ocean ridge
at the deep ocean trench
under a glacier
furthest away from the mid-ocean ridge & near a landmass
19
Wegener's evidence included fossils, mountains and glaciers on different continents.
false
true
