Let’s see what we know…
Which are you ready to answer,
and which do you need a peek?
Tectonic plate
movement may be
caused by all of the
following EXCEPT—
A slab pull
B ridge push
C convection
D magnetism
All of the following
are tectonic forces
that shape the
surface of the earth
EXCEPT—
A subduction
B spreading
C transformation
D transpiration
Let’s see what we know…
Since you could answer the last
question, can you answer this one?
The Middle East consists of mountains,
upland plateaus and valleys. These
physical features are the result of:
A erosion
B tectonic forces
C deposition
D weathering

Japan is particularly
susceptible to which of the
following hazards?
