Earth’s crust is made up of tectonic plates. This diagram shows two plates found under the Himalaya Mountains. Which of the following statements best describes the tectonic plates shown in the diagram?
a. Two convergent plates, one continental and one oceanic
b. Two convergent continental plates
c. Two divergent continental plates
d. Two divergent plates, one continental and one oceanic
Using underwater sonar, scientists create a map of the ocean floor. Data from the middle of the Atlantic Ocean reveals a large undersea mountain range. Which type of boundary caused this mid ocean ridge?
convergent
divergent
transform
subduction
Which letter represents the layer on which the tectonic plates move?
A
B
C
D
What does this figure show?
covergent boundary
divergent boundary
transform boundary
stationary plate boundary
At which of the following kinds of plate boundaries does seafloor spreading occur?
convergent
divergent
transform
stationary
What happens when the crustal plates move as shown in the figure?
An ocean forms.
Volcanic mountain ranges form.
Sea-floor spreading occurs as the oceanic plate moves.
A transform boundary forms where the subduction occurs.
The movement of tectonic plates changes the surface of the Earth. Which type of plate boundary would most likely form a mountain range?
Convergent boundary without subduction
Convergent boundary with subduction
Divergent boundary
Transform Boundary
The illustration below represents the movement of one type of tectonic plate boundary. How will Earth's surface most likely change as a result of this particular movement?
Uplift of the continental crust will occur as the result of pressure applied by the oceanic crust, which creates a hill.
The oceanic crust will push the continental crust so that a separation occurs between the two crusts.
Magma will be pushed through openings in the surface, also called a volcano, as the oceanic crust pushes under the continental crust.
As the two crusts slide past each other, the routes of rivers and streams may be changed.
The movement of Earth's plates results in changes in Earth's surface. Some of these changes occur very quickly, while others may take millions of years to form. Which of the following is most likely formed from a rapid change?
a mid-ocean ridge
a mountain range
a rift valley
a volcano explosion
Which of the following are part of earth’s plates?
Both ocean basins, which are oceanic and continents which are continental.
Continents but not ocean basins
Ocean basins but not continents
Neither ocean basins nor continents
Two of earth’s plates pressed together for many millions of years. What happened if they pressed together in a place where oceanic plate material meets continental plate material?
The continental plate material was pushed downward.
The plates were not able to move while they were pressing together and no plate material was pushed upward.
The oceanic plate material was pushed downward.
The edges of the plates were not pushed upward but they were broken into small pieces.
Plate A and Plate B are both made of continental plate material where they touch. What will happen as the plates press together?
The edges of both plates will be pushed upward as the plates continue to move toward each other and create a Mountain.
The edges of both plates will be pushed downward as the plates continue to move toward each other.
One plate will stop moving, and one plate will push upward as it continues to move toward the other plate.
Both plates will stop moving.
What will happen as continental plate material presses into another continental plate over many millions of years?
Continental plate material will always be pushed downward.
Continental plate material does not change or move.
Continental plate material will be pushed downward only if it presses into oceanic plate material.
Continental plate material will always be pushed upward into a mountain.
Based on the diagram below, which letter indicates a place where new plate material is forming?
At the boundary of the continent and ocean basin at letter A.
At the boundary where the two plates are pulling apart at letter C.
On plate 1 where B is located.
No new plate material is forming anywhere shown in the diagram.
The Rocky Mountains are known for beautiful scenery. Which processes of the Rocky Mountains most likely required the longest period of time to occur?
growth of plants and trees
large accumulation of snow on the mountaintops
formation of streams from running water
creating the mountain itself by having a large uplift of the land from tectonic forces
Tectonic plate movement can create mountain ranges. Which of the following would produce mountains?
Plates move away from each other
Plates slide past each other
Plates move toward each other
Mountains are not formed from the movement of plates
