Answers
1
Which of these happens at subduction zones?
Oceanic plates melt, increasing the magma beneath the surface.
all of the above
Oceanic plates move under continetal plates
Earthquakes and volcanoes occur
2
What makes the land adjacent to a subduction zone be more likely to experience earthquakes?
neither of these are correct
both of these are correct
Build up of magma due to the melting oceanic crust
Enegy released as the oceanic crusts grinds beneath the continental crust
3
What is the name of the plates that support all of the land on Earth?
Paper plates
Continental Plates
Pacific plates
Oceanic plates
4
What is another way to describe this type of convergent boundary?
mid ocean ridge
none of the above
transform boundary
subduction zone
5
What makes the land adjacent to a subduction zone more likely to produce volcanoes?
Enegy released as the oceanic crusts grinds beneath the continental crust
Large amount of magma created by the melting oceanic crust.
Both of these are true
neither of these are true
6
What process has caused the tectonic plates to move apart over billions of years?
continental drift
Subductifiation
Sea floor speading
Transform effect
7
What is proof that all of the continents were once one piece?
matching mountain ranges on opposite sides of oceans
They fit together
All of the above
Similar fossils found across oceans

Mid ocean ridges represent what form of plate boundary?
convergent
Transform
all of these
divergent

True
False
13
Sea floor spreading at mid ocean ridges is an example of:
All of these are correct
a Divergent boundary
a Transform boundary
A Convergent boundary
14
What is the name of the supercontinent that existed before continental drift occurred?

core
lithosphere
mantle
16
A Subduction Zone is
an area more prone to earthquakes
an example of a convergent boundary
all of these are correct
an area more likely to produce volcanoes
17
What do we call the process of making new tectonic plate?
sea floor spreading
fault making
Subduction
divergent plate formation
18
What type of boundary is the San Andreas Fault in California?
convergent fault
divergent fault
Thrust fault
transform fault
19
Where might we find this type of boundary?
subduction zone
mid ocean ridge
All of these
San Andreas fault
20
Which are thicker, oceanic plates or continental plates?
They are both the same.
Continental
Oceanic
21
What type of plate boundary produces mountains like Mt. Everest?
convergent boundaries
divergent boundaries
Transform boundaries
all of these
22
What kind of boundary does this represent?
Seafloor boundary
convergent boundary
Divergent boundary
Fault boundary
23
How are oceanic islands like the Hawaiian islands formed?
Due to convergent boundaries
In subductions zones
Due to continental drift
By the mantle burning through the crust
24
According to our notes, Earthquakes are created by:
Plates moving against each other at transform boundaries
None of these are true.
All of these are true
Oceanic plates moving beneath continental plates in subductions zones
25
The big island of Hawaii is the tallest mountain in the world.
False
True
26
What happens at transform boundaries?
Earthquakes occur often
Magma builds up as crust is melted
The plates slide in opposite directions rerleasing huge amounts of energy
Two of these are correct
27
What do we call the gradual movement of the tectonic plates?
Subduction
continental drift
pangea
sea floor spreding
