What are plates?
a)
The plates are made of the outer layer of the Earth and they are under the mantle
b)
There is only one plate on Earth and it is on top of the mantle
c)
The outer layer of the Earth is made of plates that are on top of the mantle
d)
The outer layer of the Earth is made of plates and they are under the mantle
2.
How do we know where the plate boundaries are?
a)
They are shown by lines on a map
b)
They are shown by lines of earthquakes
c)
They are shown by lines on the bottom of the sea
d)
We don't know where the plate boundaries are
3.
In the Plate Motion SIM, what does the purple line (at F) mean?
a)
The purple line is where the plate boundary is
b)
The purple line is where the volcanoes form
c)
The purple line marks where the cross section is
d)
The purple line marks where earthquakes form
4.
In this cross section, what does the green line show?
a)
The green line shows where the plate boundary is
b)
The green line shows where the cross section is
c)
The green line shows where the ocean starts
d)
The green line shows where the land ends
5.
What is happening with the plates in this cross section?
a)
The cross section shows the plates are not moving
b)
The cross section shows the plates are moving apart (diverging)
c)
The cross section shows the plates are moving sideways to each other
d)
The cross section shows the plates are moving together (converging)
6.
If the mantle were solid rock, like in this picture from the SIM, what would the plates do?
a)
The plates would move faster
b)
The plates would move slower
c)
The plates would not move
d)
There would be no difference
7.
What is the mantle actually like?
a)
Rock in the mantle is soft and squishy like silly putty
b)
Rock in the mantle is solid
c)
Rock in the mantle is liquid
d)
Rock in the mantle is made of crystals
8.
What is a mid-ocean ridge?
a)
A mid-ocean ridge is a place in the ocean where plates are moving together (converging)
b)
A mid-ocean ridge is a place in the ocean where plates are moving sideways
c)
A mid-ocean ridge is a place in the ocean where plates are not moving
d)
A mid-ocean ridge is a place in the ocean where plates are moving apart (diverging)
9.
Where is a trench found?
a)
A trench is found in the ocean where two plates are diverging (going apart)
b)
A trench is found in the ocean where two plates are moving sideways to each other
c)
A trench is found in the ocean where two plates are converging (coming together)
d)
A trench is found in the ocean far away from a plate boundary
10.
Where are most big earthquakes and volcanoes found?
a)
Most big earthquakes and volcanoes are found along plate boundaries
b)
Most big earthquakes and volcanoes are found far away from plate boundaries
c)
Most big earthquakes and volcanoes are found mostly in the middle of plates
d)
Most big earthquakes and volcanoes are found on Mars
11.
Africa and South America are moving farther apart because
a)
they are on plates that are converging
b)
they are on plates that are moving sideways to each other
c)
they are on plates that are diverging
d)
they are not actually moving at all
12.
South America and Africa were once together as one place. What do you think is the BEST evidence for this?
a)
Africa and South America look like they could have fit together
b)
Africa and South America have a plate boundary between them
c)
Fossils of Mesosaurus (an animal that could not swim across the ocean) are found in both Africa and South America
d)
They were never together, that's silly, continents can't move

Convergent (moving together)
b)
Divergent (moving apart)
c)
Transform (moving sideways)
