Questions and Answers
  • 1. 
    Scientists found that the continents were moving apart from each other due to magma rising out of mid-ocean ridges, and they called this:
    • A. 

      Sea floor spreading

    • B. 

      Sea floor rising

    • C. 

      Changing sea floor

    • D. 

      Underwater volcanos

  • 2. 
    The Earth's continents were once connected in one giant continent called:
    • A. 

      Eurasia

    • B. 

      Indo-Australia

    • C. 

      Pangaea

    • D. 

      Pacifica

  • 3. 
    The Earth's crust is divided into 7 major plates, which include all of the continents. Along which two plates do we see major earthquake activity?
    • A. 

      Pacific and North/South American

    • B. 

      Pacific and Eurasian/Indian

    • C. 

      South American and African

    • D. 

      A and B

  • 4. 
    Wegener's old theory, called sea floor spreading, was found too simplistic because it did not explain how the continents would move. It was replaced by a theory called:
    • A. 

      Plate Tectonics

    • B. 

      Crustal Forces

    • C. 

      Paleomagnetism

    • D. 

      Weather forces

  • 5. 
    Plate tectonics is our current theory of how the movement of continental masses relates to the movement of ocean basins. This movement explains many phenomena, such as:
    • A. 

      Earthquakes

    • B. 

      Volcanoes

    • C. 

      Weather patterns

    • D. 

      All of the above

  • 6. 
    Plate margins are places where much activity occurs. Earthquakes occur, for example, along convergent margins, where plates are:
    • A. 

      Moving apart

    • B. 

      Sliding past each other

    • C. 

      Colliding

  • 7. 
    Volcanoes occur in similar locations to earthquakes, and are common along plate boundaries. Sixty percent of volcanoes occur surrounding the Pacific Ocean, a location called:
    • A. 

      "The hot zone"

    • B. 

      "The Ring of Fire"

    • C. 

      "The Volcano Zone"

  • 8. 
    Plate tectonics can also be the direct cause of forming:
    • A. 

      Lakes

    • B. 

      Streams

    • C. 

      Mountains

    • D. 

      Oceans

  • 9. 
    Plate tectonics, or the movement of pieces of Earth's crust, is thought to be caused by:
    • A. 

      Volcanoes

    • B. 

      Earthquakes

    • C. 

      Convection currents in Earth's mantle

    • D. 

      Hot spots
