PLATE TECTONICS AND PHYSICAL HAZARDS

MULTIPLE-CHOICE QUESTIONS

  1. What direction is the Pacific Plate currently moving, based on the chain of Hawaiian Islands with only the easternmost island active? 
  1. to the northeast
  2. to the northwest 
  3. to the southeast
  4. to the southwest
  5. It is not moving; the chain of islands is not related to the active one.

ANSWER: b

  1. Before people understood plate tectonics, what evidence led some scientists to believe in continental drift? 
  1. Rocks on the ocean floor are oldest in the center, becoming progressively younger toward each continent.
  2. Rocks on the continents can be traced through the ocean floor to the other side.
  3. Anthropologists have found human carvings in Africa that match those in Brazil.
  4. Glaciers near the mouth of the Amazon River in Brazil carried distinctive rocks into South Africa, demonstrating that those countries were once connected.
  5. Ages of bedrock formations match across the Atlantic Ocean.

ANSWER: e 

  1. Which of the following was NOT used as early evidence for continental drift?
  1. ages of bedrock formations that match across the Atlantic Ocean
  2. match of coastlines across the Atlantic Ocean 
  3. match of rock formations across the Atlantic Ocean
  4. match of ages of continental rocks across the Atlantic Ocean
  5. the fact that the magnetic pole shifts from north to south 

ANSWER: e 

  1. Which of the following is true?
  1. The mantle is denser than the lithosphere.
  2. The lithosphere is denser than the mantle.
  3. The asthenosphere is the more rigid equivalent of the mantle.
  4. The asthenosphere is the more plastic part of the mantle.
  5. The mantle is everywhere more rigid than the crust.

ANSWER: d 

  1. Which of the following is true?
  1. Oceanic rift zones are found only in the center of the oceans.
  2. Rift zones are found only in the ocean basins.
  3. Rift zones are areas where oceanic crust is formed. 
  4. Rift zones are the oldest parts of the oceanic crust.
  5. Rift zones mark the boundaries between oceanic and continental crust.

ANSWER: c 

  1. Which of the following is NOT true?
  1. Subduction zones are areas where ocean floor descends into the mantle.
  2. Subduction zone activity includes very large earthquakes.
  3. Subduction zone activity leads to active volcanoes. 
  4. Subduction zones are areas where ocean floor rocks are formed. 
  5. Subduction zones are marked as the deepest parts of the oceans.

ANSWER: d 

  1. Which of the following is true?
  1. Transform faults show dominantly vertical movement.
  2. Transform faults are only in the ocean basins.
  3. Transform faults are areas of spreading and new crustal generation.
  4. Transform faults change with time from horizontal to vertical motion.
  5. Transform fault motion typically ends abruptly at both ends. 

ANSWER: e 

  1. What does oceanic lithosphere consist of? 
  1. basalt on top of peridotite 
  2. only basalt
  3. only peridotite
  4. basalt and peridotite in layers of variable thickness, in some places above, in others below
  5. partly basalt and partly granite

ANSWER: a 

  1. Along which type of lithospheric plate boundaries are earthquakes common?
  1. only convergent (subduction zones)
  2. only divergent (spreading zones)
  3. only transform
  4. only divergent and transform
