Oceanic crust is...
thicker than continental
thinner than continental
more dense than continental
less dense than the Mantle
less dense than continental
made of mostly granite
made of mostly basalt

Continental crust is...
less dense than the Mantle
less dense than oceanic
thinner than oceanic
made of mostly granite
more dense than oceanic
thicker than oceanic
made of mostly basalt
Question 4
4.
Where is the temperature in the Mantle the greatest?

Question 8

Click and drag each item to the corresponding category. (Items may be used more than once or not be used at all.)
plates moving in opposite directions
San Andreas Fault
Mount St. Helens
ground above caves in
East Africa Rift
lift and rip the crust
Mid-Atlantic Ridge
creation of new crust
Oceanic Divergent
Continental Divergent
Transform
Question 9
9.
Describe how a 'Strike-Slip Fault' is different from a 'Transform Fault'.
Question 10
10.
What is the name of the process of one tectonic plate going under another?
transform
convergent
subduction
translation
tranformation
Question 11
11.
Oceanic Crust and Continental Crust converge.
Which goes under, and why?
Question 12
12.
Why does the top of the continental crust deform and fracture in a subduction zone?
because when plates move they cause deformation
tsumanis occur because of the deformation
cracks because of the intense friction between the two plates
continental crust is less dense and therefore cracks and deforms
Question 13
13.
The crust melting from the subducting plate causes magma to 'float up' to the surface and create volcanoes.
True; because density of the surrounding crust is lower than the magma
False; because melted crust is more dense than solid crust
True; because density of the magma is lower than the surrounding crust
False; because density of the surrounding crust is lower than the magma
Question 14
14.
What is the driving force behind the movement of the tectonic plates?
Question 15
15.
When oceanic and oceanic plates converge, the __________ plate tends to subduct because it is often the one with the __________ density.
Question 16
16.
Check off anything that makes the following statement true.
When continental and continental plates converge ...
they typically form mountains
neither plate is dense enough to go into the mantle
neither technically 'subducts'
they typically form volcanoes
they create a melange of rock
Question 17
