Multiple Choice

Multiple Choice

Tectonic plates can be moving towards one another or away from one another. Which of the following crustal features is formed when two plates are moving away from one another?

• Volcanic island arc

• Mid-ocean ridge

• Mountain range

• All of the above

Multiple Choice

In which diagram do the arrows best represent the motions of Earth's crust at the Peru-Chile Trench?

Multiple Choice

Which type of boundary is shown in the picture?

• Convergent boundary

• Divergent boundary

• Transform boundary

• Convection boundary

Multiple Choice

The map shows California and the section of the San Andreas Fault. What is the primary geologic process occurring along the San Andreas Fault?

• Transform movement

• Spreading movement

• Subduction

• Convergence

Multiple Choice

The San Andreas fault is a transform fault. The map below shows a student’s approximation of where the fault line crosses through the United States. Students were asked to make maps predicting which way land would most likely move over thousands of years.Which map best predicts the likely movement of land along the fault line over thousands of years?

Multiple Choice

A mid-ocean ridge separates the Pacific plate and the Nazca plate off the western coast of South America.Which statement best describes the relative motions of the Pacific and Nazca plates?

• The Pacific and Nazca plates are both moving to the east.

• The Pacific and Nazca plates are both moving to the west.

• The Pacific plate is moving to the west, and the Nazca plate is moving east

• The Pacific plate is moving to the east, and the Nazca plate is moving to the west.

Multiple Choice

The diagram shows a model of the movement of two tectonic plates. When the plates collide, one plate often moves below the other plate. The rising magma that can result from this type of plate movement may produce —

• fossil layers

• volcanic islands

• deep-sea sediment

• seafloor spreading

Multiple Choice

The model below shows two continental plates. The folded mountains in this model form at which type of plate boundary?

• convergent boundary

• divergent boundary

• transform boundary

• subduction boundary

Multiple Choice

The thick black lines on the map below show the locations of mid-ocean ridges.Which geologic feature is most likely to form at a mid-ocean ridge?

• Peninsula

• Volcano

• Delta

• Plateau

Multiple Choice

The San Andreas Fault is a transform fault that is located at the border of the North American Plate and the Pacific Plate. What would most likely form along this fault if it were a convergent boundary instead of a transform fault?

• Rivers

• Mountains

• Rift valleys

• Mid-ocean ridges

Multiple Choice

The map below shows the locations of four active volcanoes in the Caribbean Sea.What do these volcanoes indicate about plate tectonics in the region?

• The volcanoes form an island arc, indicating a converging plate boundary.

• The volcanoes form a line, indicating a diverging plate boundary.

• Two plates are moving past each other, causing faulting and magma formation.

• Two plates are moving apart, creating new seafloor.

Multiple Choice

The image shows a plate boundary. Arrows have been added to indicate the movement of the plates.What plate boundary feature is also shown?

• A ridge formed by an inactive convergent boundary

• A valley forming at an active divergent boundary

• A fault forming at an active transform boundary

• A volcano formed by an active transform boundary

Multiple Choice

The diagram shows the cross section of two crustal plates and the boundary between them. At this plate boundary, the crustal plates are –

• diverging

• converging

• transforming

• subducting

Multiple Choice

Which cross section below best represents the crustal

plate motion that is the primary cause of deep ocean

ridges and volcanic seafloor spreading?

Multiple Choice

The diagram below shows the location of mid-ocean ridges and the age of some oceanic bedrock near these ridges.The age of oceanic bedrock on either side of a mid-ocean ridge is supporting evidence that at the ridges, tectonic plates are –

• diverging

• locked in place

• converging

• being subducted

Multiple Choice

The Himalayan mountains are shown on the map below. Four students were asked to identify the geologic process that caused this mountain range to form. Their responses are shown in the table below.Which student correctly identified the geologic process that formed the Himalayan mountains?

• Student 1

• Student 2

• Student 3

• Student 4

Multiple Choice

Which of the following is NOT evidence for the plate tectonic theory?

• Glacial evidence found on places that are now hot

• Fossils found across continents that are similar

• Magnetic poles flipping showing seafloor spreading

• The shape of the continents shows they do not fit together

Multiple Choice

Which type of boundary is shown in the picture?

• Convergent boundary

• Divergent boundary

• Transform boundary

• Convection boundary
