1. The boundary Juan de Fuca plate is compressing against the North
American plate resulting to the formation of volcanoes and mountain
ranges. The Juan de Fuca and North American plates have ________________
type of plate boundary.
A. Divergent B. Convergent C. Transform D. Faulting
2. What are colliding when plateaus and mountains ranges are formed?
A. Continent- ocean convergent plate boundary
B. Ocean-Ocean convergent plate boundary
C. Continent-continent plate boundary
D. Cannot be determined
3. What causes the other plate to subduct beneath the other plate during
convergence?
A. The material of the other plate is denser than the other.
B. The plates have the same components and the overriding is by chance.
C. The plate that sinks beneath the other moved first than the other.
D. The overriding plate is heavier than the other plate.
4. The following shows the difference between convergent plate boundary and
divergent plate boundary EXCEPT _______________________.
A. Plates in a divergent plate boundary is drifted away while in a convergent
plate boundary is moving towards each other.
B. A divergent plate boundary produces new crust while a convergent
boundary destroys old crust.
C. A divergent plate boundary forms rift valley while a convergent boundary
forms trenches.
D. A divergent plate boundary usually occurs in the seafloor while a
convergent boundary occurs only on the continental crust.
5. How are the plate boundaries classified?
A. Through the movements of the plates.
B. Through the type of continents involved in the movement of the plates
C. Through the movement of the asthenosphere beneath the lithosphere
D. Through the location of the plates on the world map
6. During collision of two plates, subduction does NOT occur. Why?
A. The continental plates have the same density causing the plates to
compress each other instead of subducting.
B. The continental plates do not have water to push down the other plate
which causes subduction.
C. The continental plates are pushed upward by the magma as they collide.
D. The continental plates are slowly moving towards each other which
prevent the other plate from subducting.
7. Which describes BEST the boundary of a lithospheric plate?
A. All the edges of a plate exhibit similar movements.
B. Plate boundaries are gradually drifting away from each other.
C. A plate may have a different boundary on its edges depending on its
movement.
D. The edges of the plate may have different types of boundary due to its
interaction with the surrounding plates.
8. Which describes the Philippine sea plate?
A. The boundary is convergent because of the trenches.
B. The boundary is transform due to the Philippine fault line in the middle of
the Philippines.
C. The boundary is transform due to the earthquakes and typhoons.
D.The boundary is divergent because the Philippines is an archipelago.
9. What type of boundary exists if the edges of Eurasian plate is compressing
the Philippine sea plate?
A. Plate boundary C. Divergent boundary
B. Transform boundary D. Convergent boundary
10.Which plate boundary forms rift valley due to tension?
A. Continent convergent boundary C. Divergent plate boundary
B. Transform plate boundary D. Convergent plate boundary
11. During the collision of two plates, there is a tendency that a plate subducts
beneath the other plate. If the subduction continues, even the overriding
plate may sink and form a deep trench. What causes the continuous
subduction of the plates?
A. The melted plate forms convection currents that pulls down the plates
together.
B. The overriding plate is pushing down the subducted plate.
C. The interacting plates locked up due to friction making them to sink
together.
D.The compression of the plates makes the subducted plate to slide down
the asthenosphere.

A. Ocean-ocean C. Ocean-continent
B. Continent-continent D. All types of plate can be subducted
15.What type of resisting force may exist to prevent the compression of the
overriding plate?
A. Slab resistance B. Slab suction C. Slab pull D. Drag force
