      1. Albert Einstein
      2. Afredo Wegner
      3. Alfred Wegener
      4. Alfred Wenger

    2. Over the last million years the continents, which were once joined into one large landmass, moved into their current configuration These movements were caused by “ . . . 
      lithospheric plates moving from convective flow in the mantle.

      1. lithospheric plates moving from convective flow in the mantle
      2. the slow movement of the continents floating on the ocean
      3. large volcanic eruptions, earthquakes, and impacts from asteroids
      4. the slow erosion of the continents by oceans, rivers, and lakes

    3. What are the main layers of the earth?
      1. Crust
      2. Mantle
      3. Cruste
      4. Core
      5. Namtle
      6. Cortex

    4. Before Wegener's theory, how did scientists believe animals got from Africa to South America?
      1. They flew over it
      2. They got transported by humans
      3. Land bridge

    5. Continental crust is “ . . . 
      ” than oceanic crust.
      1. Hotter
      2. Thinner
      3. Thicker
      4. Colder

    6. People accepted the idea of continental drift.
      1. False
      2. True

    7. The Theory of Plate Tectonics is based on “ . . . 
      evidence of sea floor spreading.
      1. volcanic activity along coastlines
      2. topographic mapping of mountain ranges
      3. evidence of sea floor spreading
      4. an analysis of soil at the plate boundaries

    8. What did Alfred name the single piece of land?
      1. Pangeo
      2. Pangea
      3. Pancake
      4. Prenstea

    9. Which of the following is NOT evidence of plate tectonics?
      1. distribution of fossils
      2. the shape of the continents
      3. rain forest depletion
      4. location of earthquakes

    10. Which of the following is not a divergent plate boundary?
      1. The Mid-Atlantic Ridge
      2. The East Pacific Rise
      3. The San Andreas fault
      4. The Great Rift Valley of East Africa

    11. What was one reason that Alfred thought that the continents were one piece of land and then drifted away?
      1. Some continents fit together just like a jigsaw puzzle
      2. He thought that it seemed like a nice idea
      3. Because fossils of the same animals were found on opposite sides of the world
      4. He had a dream about it

    12. Which of the following are not associated with convergent plate boundaries?
      1. Island arcs
      2. Volcanoes
      3. Rift valleys
      4. Deep-focus earthquakes
      5. Deep-sea trenches

    13. What continents fit almost fully like a jigsaw puzzle?
      1. Europe and South America
      2. Africa and South America
      3. Europe and Australia
      4. North and South America

    14. Subduction is when “ . . . 
      One Plate Slides Under Another.
      1. New crust is formed
      2. Earthquakes occur along a transform boundary
      3. One plate slides under another
      4. New islands are formed

    15.  What is ONE major fault in California?
      1. San Jose Fault
      2. San Antonio Fault
      3. San Francisco Fault
      4. San Andreas Fault

    16. Why do earthquakes usually occur at plate boundaries?
      1. The rock on the edges of tectonic plates is soft and gives in easily to various pressures
      2. The boundaries between tectonic plates have been seismically active for millions of years
      3. Rock in environments near tectonic plates boundaries experience little stress
      4. Rock in environments near tectonic plate boundaries experience great stress

    17. What is convection?
      1. When something gives off heat
      2. When something absorbs heat
      3. When hot materials rise and colder ones sink

    18. The process that continually adds new crust is “ . . . 
      Sea-Floor Spreading
      1. Sea-floor spreading
      2. Earthquakes
      3. Subduction
      4. Convection

    19. What causes the seafloor to spread apart at mid-ocean ranges?
      1. Hot magma rises through the boundary at the mid-ocean ranges, creating new rock and pushing apart the plates
      2. The waves in the ocean pull the plates away from each other, This happens at the mid-ocean ranges
      3. The Earth's magnetic field is so strong it pushes apart the iron-filled rocks at the mid-ocean ranges
      4. The Earth is growing in size (though we don't know why) and the mid-ocean ranges are where the crust has cracked to allow the Earth to get bigger

    20. The inner-most part of the Earth is known as the “ . . . 
      Inner Core.

      1. Inner Core
      2. Outer Core
      3. Mantle
      4. Continental Crust
      5. Oceanic Crust
