8.9ABC Earth and Space:Plate Tectonics TEST

8.9A- Scientists recently discovered that rocks collected from the Franklin Mountains in West Texas and rocks collected from mountains in eastern Antarctica were exactly the same age. Further research showed that the rocks were chemically and geologically the same and came from the same magma source. This discovery provides evidence of —

• coastal erosion

• plate tectonics

• ocean currents

• glacial melting

8.9C- This satellite image shows a ship channel between South Padre Island and Boca Chica beach in South Texas. Sand is sometimes removed from the ship channel through a process called dredging to make it easier for ships to travel through. Recently sand from the bottom of the channel was moved to area beaches. Without this transfer of sand, what would most likely occur in this area in the future?

• The ship channel would become deeper, and the island would move west toward the mainland.

• The ship channel would become shallower, and the beach would become narrower.

• The ship channel would become narrower, and the island would become completely covered with water.

• The ship channel would become wider, and the island would sink into the Gulf of Mexico.

8.9B- This 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

• deep-sea sediment

• volcanic islands

• seafloor spreading

8.9C-The points labeled W and Y on the topographic map below show the campsites of two families. Each family hiked to the elevation on the map marked X. The arrows show the paths taken by both families. What was the change in elevation, to the nearest ten meters, for the family that took the steepest path to Point X?

• 80m

• 100m

• 120m

• 140m

8.9B- The Himalayan mountains are shown on the map. Four students were asked to identify the geologic process that caused this mountain range to form. Which student correctly identified the geologic process that formed the Himalayan mountains?

• Student 1-Two continental plates converging

• Student 2-An earthquake in a subduction zone

• Student 3-A tectonic plate moving over a hot spot

• Student 4-Movement at a transform fault boundary

8.9B- 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 volcano formed by an active transform boundary

• A valley forming at an active divergent boundary

• A fault forming at an active transform boundary

8.9C-This satellite photo shows 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

8.9C- A student stands at the point marked X on the topographic map below. What height in meters must the student climb in order to reach the top of the hill?

• 203m

• 253m

• 303m

• 353m

8.9B- 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?

8.9B- 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 is moving to the west, and the Nazca plate is moving to the east.

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

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

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