Processes And Landforms Along Plate Boundaries Flashcards
When magma in the earth’s mantle develops a great pressure, the ground above it is pushed upward. If this happens in the middle of an ocean, what landform is produced?
A. mountain
B. volcanic island
C. volcano
D. continent
B
The tall landform created when two continental plates converge is called,
A. mountain range
B. volcanic arc
C. rift valley
D. Oceanic ridge
A
It is a plate that dives down under a less dense plate during subduction.
A. subducting plate
B. continental plate
C. mantle
D. overriding plate
A
Materials in the mantle flow up and down. Which of the following best describes the mantle?
A. a solid layer
B. partially liquid
C. a metallic layer
D. very hot layer
B
Which of the following happens when plates diverge or move away from each other?
A. The crust is destroyed.
B. New crust is produced because magma rises, then cools off and turns into solid.
D. The mantle rises.
C. Earth’s size changes because mountains are added on the earth’s surface
B
A rift valley is formed simultaneously with which of the following type of plate boundary?
A. Convergent
C. Transform fault
B. Divergent
D. Both convergent and divergent
B
How do the plates move when we feel that the ground is shaking?
A. toward each other
B. away from each other
C. slide past each other
D. all of the above
D
It is a landform produced when two continental plates converge.
A. volcano
B. fault
C. mountain
D. volcanic island
C
Most transform fault boundaries are found in the oceans; a few are on the continents. An example of this type is the San Andreas Fault located in
A. Marikina, Philippines
B. California, USA
D. Saudi Arabia
B
It is otherwise known as an underwater mountain.
A. oceanic ridge
B. trench
C. hill
C. Japan
D. volcanic island
A
It is a chain of volcanoes developed parallel to a trench or a crack under the
ocean. A. mountain range
B. volcanoes
C. volcanic island are
D. mountainous
C
It is formed when ocean water flips upward, sometimes up to certain meters high, due to the great push caused by convergence of plates.
A. wave
B. tsunami
C. tides
D. storm
B
It is the point where two plates meet or collide while converging.
A. collision zone
B. sinking point
C. subduction zone
D. meeting point
A
The place where a subducting plate reaches the mantle during convergence.
A. collision zone
B. subduction zone
C. mantle plume
D. magma
B
The word used to refer to the shaking of the ground due to any activity in the lithosphere.
A. intensity
B. earthquake
C. Volcanism
D. wave
B
When an oceanic crust converges with a continental crust, a crack between the crusts underwater, a ____ is formed
Trench
is the process by which a plate dives under a less dense plate.
Subduction
Due to the heat in the mantle, the magma builds up a pressure that
enables it to push the ground above it. The column of rising magma is called a
mantle plume.
group of volcanoes,
Volcanic arc
As plates pull away from each other, a vertical space that may extend deep down into the lowest layer of the crust is created. It is a
Rift valley
The force of separation creates a
Tension zone
Plate divergence is believed to be a slow continuous process. As the plates move away, the gap between them increases. While this happens, materials from the mantle may rise, filling up the space. These materials pile up near the tension zone forming mountain-like structures called
Oceanic ridges
filled-up space between the plates becomes a new seafloor. This process is known as
Seafloor spreading
