The diagram below models two tectonic plates sliding past one another. This type of plate
movement is common with oceanic plates. As the plates push against one another, pressure
builds up in the form of tension. All of the tension is released when the plates begin to move.
According to the information and diagram above, which force is responsible for the plate
movement?
Balanced
Gravitational
Frictional
Unbalanced
Students examine a map that shows the movement of the two tectonic plates.
Each student writes a description of the tectonic activity and why they think it is occurring.
Which explanation best describes the impact of Newton’s Laws on the movement of these
plates?
The North American Plate is subducting underneath the Eurasian Plate because equal and
opposite forces are acting on them.
The forces acting on both plates cause them to diverge until they are acted upon by
another force.
The Eurasian Plate and the North American Plate are converging because the forces
acting on them are balanced.
Balanced forces are acting the Eurasian Plate and the North American Plate causing them
to diverge.
The image models the process of Pangea breaking up into modern day continents.
Which of the following best explains why Pangea broke apart into modern day continents?
Earthquakes and volcanoes formed between the continents.
Changing climate caused ice to form between the plates.
Balanced forces caused a change in the motion of the plates.
The plates underlying the continents were already in motion.
Scientists believe that convection currents within the____ are responsible for the movement
of the plates that form the Earth's crust.
Asthenosphere
Lithosphere
Inner Core
Outer Core
Which two continents did Alfred Wegener think looked like they fit together like puzzle
pieces?
North America and South America
Europe and Africa
North America and Europe
South America and Africa
Which scientist is credited for first proposing Continental Drift Theory?
Albert Einstein
Alfred Wegener
Abrahan Ortelius
Harry Hess
Alfred Wegener noted that fossils from a particular type of reptile were found on both sides
of the Atlantic Ocean. Which of the following would be the best explanation of how
this occurred?
The reptiles swam across the ocean.
The Atlantic Ocean did not exist in earlier times.
The reptiles walked across a giant land bridge that has weathered away.
The reptiles walked across an ice bridge located near the equator.
Scientists discovered trilobite fossils in Oklahoma and Morocco, as illustrated on the map
below. Additional research in these areas shows that the rocks in Oklahoma and Morocco
surrounding these fossils are physically and chemically similar.
The discovery of trilobite fossils in Oklahoma and Morocco provide evidence of —
plate tectonic movement
volcanic eruptions
weathering and erosion
weathering and deposition
Which of these landforms is most likely to be found at a convergent boundary?
Fault Line
Mid-ocean ridge
Mountain
Rift Valley
The most recently formed crust of the Earth would be found —
where plates moving sideways passed each other
where one plate is going under another plate
where two plates are pushing directly toward each other
where two plates are moving away from each other in opposite directions
Which of the following geological features could form when two plates collide?
Trench
Mid-ocean ridge
Transform fault
Delta
In an area known as The Ring of Fire, volcanic island chains have formed in the Pacific
Ocean. What most likely caused this to happen?
Convergent plate boundary
Divergent plate boundary
Transform plate boundary
Mantle hot spot
The diagram below models the movement of two tectonic plates.
What is occurring as a result of the plate collision?
A mid-ocean ridge is forming.
Subduction is occurring because oceanic crust is denser than continental crust.
A divergent boundary is forming.
A transform boundary is forming due to two plates sliding past one another.

The diagram below models two continental plates.
Which type of continental plate movement formed the mountains modeled in the above
diagram?

Subduction
The Aleutian Arc is a large volcanic arc which consists of a grouping of active and dormant
volcanoes that have formed along the Aleutian Trench.
The Aleutian Arc is a distinguishing feature of the state of Alaska illustrated above. Alaska is
part of the North American Plate. To the South of the Aleutian Arc is the Pacific Plate. The
Aleutian Arc was formed as the Pacific Plate traveled North and the North American Plate
traveled West.
Based on the information above, which type of plate boundary caused the formation of the
Aleutian Arc?
Divergent Boundary
Transform Boundary
Convergent Boundary
Strike-Slip Fault Boundary
The satellite image below shows the Appalachian Mountains located in Pennsylvania. The
Appalachian Mountains formed when the North American and African plates formed a
convergent boundary. The two plates have since formed a divergent boundary over millions
of years as the continents have drifted away from each other. Weathering, erosion, and the
change in type of plate boundary have significantly changed the shape of the Appalachian
Mountains over time.
Which statement below describes how these mountains will most likely change over time?
The mountains will increase their elevation over time.
The mountains will become more steep and jagged over time.
The mountains will become rounder and less steep over time.
The mountains will spread into the state of Louisiana.
The diagram below is a portion of a topographic map.
According to the diagram above, which direction would you expect a delta to be formed?
To the left
To the right
To the top
To the bottom
Students modeled the formation and weathering of a volcano in the ocean. The students
drew a line around an aquarium to represent sea level. Clay was pushed through a hole in the
bottom of the aquarium to represent the formation of the volcano. Students then cut
sections of the clay, using a small wire, to represent weathering of the volcanic formation.
Throughout the investigation, students took a series of pictures of their model.
What order of topographic maps best matches the order of the model pictures?
A topographic map is shown below.
Observe the topographic map above. What is the elevation in meters at point Z?

1200
1080
1140
