Topo Maps and Plate Boundaries

The San Andreas Fault is a transform fault.  The map 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.

• A
• B
• C
• D

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 site
• A fault forming at an active transform boundary
• A volcano formed by an active transform boundary

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

The satellite photo show San Francisco, California, which has many miles of coastline and an inland bay.  Which area of the coastline has most likely experienced the greatest effect of erosion from waves over hundreds of years?

• Area N
• Area P
• Area S
• Area T

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

A student stands at the point marked x on the topographic map.  What height is meters must the student climb to reach the top of the hill?

• 300 m
• 303 m
• 253 m
• 250 m

The topographic map shows the location of a park ranger at Point X when a message is received that an injured hiker needs help at Point Z.  Which of these is the closest to the difference in elevation between the locations of the ranger and the injured hiker?

• 2,050 m
• 450 m
• 910 m
• 3,650 m

Based on the map volcanic activity would most likely be found at...

• Boundary W

• Boundary Z

• Boundary Y

• Boundary X

How does agricultural activity most likely affect the surface water of an area?

• Excess crop fertilizer is carried by runoff, causing excess growth of water plants

• Excess crop material accumulates on the riverbanks, slowing the movement of river water

• Crops reduce erosion, increasing the amount of soil in the water

• Crops absorb water from the soil, causing the remaining water to contain more salt

Which student correctly identified the geologic process that formed the Himalayan Mountains?

• Student 1

• Student 2

• Student 3

• Student 4
