Transform
2
What event do you predict will occur at the boundary shown?
an earthquake
a mountain range formation
volcanic island formation
trench formation
3
A divergent boundary is -
subducting.
pushing together.
pulling apart.
sliding past.
4
What type of plate boundary exists in the middle of the Atlantic Ocean and what feature is created there??
Transform & San Andreas Fault
Divergent & Mid-Atlantic Ridge
Convergent & Subduction
Convergent & Mountain building
5
The type of tectonic plate boundary involving a collision between two tectonic plates
normal boundary
convergent boundary
divergent boundary
transform boundary
6
What type of boundary exists along the San Andreas Fault where many earthquakes occur?
transform
convergent
trench forming
divergent
7
Why is a Oreo cookie a good model for plate tectonics?
There are two types of crust.
The crust is solid and brittle and floats on the astenosphere.
The crust has plasticity and is hot.
The crust is brown and the mantle is white.
8
How does the divergent movement of two plates affect the ocean basin between them?
The size of the ocean basin increases.
The ocean basin does not change.
The height of the ocean basin increases.
The size of the ocean basin decreases.
9
Why is this called the "Ring of Fire"?
Many earthquakes and volcanoes occur aling thes eplate boundaries.
Lots of fires erupt there.
Earth's layers are hotter in that area.
The Fire Brigade is there.

subduction
sea floor spreading
transform boundary

transform
12
What type of boundary most likely exists along the "Ring of Fire"?
a convergent boundary
a transform boundary
a divergent boundary
a rifting boundary
13
Which type of boundary is occurring in the diagram?
a strike slip boundary
a divergent boundary
a convergent boundary
a transform boundary
14
Which of the following contributes to the movement of Earth's tectonic plates?
magnetic-pole reversals
faults in mountain ranges
convection currents below the lithosphere
All of the above
15
What is often the result of subduction?
a volcano
a folded mountain
mid-ocean ridge
a fault-block mountain
16
The Himalayan Mountains began forming as a result of which type of plate boundary?
subduction
divergent
transform
convergent
17
Which of the following occurs along transform boundaries?
volcanoes
earthquakes
mountain building
subduction
18
Continental mountain ranges usually form at
divergent boundaries
normal boundaries
convergent boundaries
transform boundaries
19
Which geological feature is caused by two continental plates colliding?
canyon forming

20
What type of boundary is responsible for seafloor spreading and the formation of mid-oceanic ridges?
Subvergent
Convergent
Divergent
Transform
21
What type of landform occurs where two tectonic plates with CONTINENTAL crust spread apart?
a fault line ridge
a mountain
a mid-ocean ridge
a rift valley
22
A subduction zone creates a __________ and __________.
trench; volcanoes
continent; oceans
mid-ocean ridge; mountains
earthquake; tsunamis
23
Why does oceanic crust typically subduct under continental crust when the two converge?
The oceanic crust is cooler.
The oceanic crust is denser and heavier.
The oceanic crust is thinner.
The oceanic crust is less dense.
