a. Pangaea Ultima b. Gondwanac. Pangaead. Laurasia

3. Heated material expands and rises, then cools. As it cools, it becomes denser and falls. This circular movement of material is called _

  1. conductionb. radiation c. convection currents d. thermodynamics

4. The theory that states that the continents were once connected but drifted apart over time is called...

a. Plate Tectonic Theoryb. Theory of Relativity c. Continental Drift Theory

5. What is the name of the process where 2 plates separate in the ocean whichcreates new crust?

a. sea-floor spreadingb. upliftc. magnetismd. subduction

6. Some volcanoes are formed at ______zones where a denser oceanic plate sinks beneath a less dense continental plate.

a. sink hole b. convergent c. subduction d. trivergent

7. ______are large slabs of rock that sit beneath the oceans and continents.

a. continental crust b. oceanic crust c. magma d. tectonic plates

8. How did the Himalayan Mountains form?

a. when 2 plates collideb. when 2 plates separatec. when 2 plates slide past each other

9. What is a fault? (either describe in words or draw a picture)

______

10. What occurs along fault lines? ______

a. earthquakes b. mountain ranges c. islands d. oceans

  1. One piece of evidence that supports the Theory of Plate Tectonics is the discovery of what in both South America and Africa?
  1. Insects on both continents have similar feeding habits
  2. The rates of sedimentary rock formation are similar
  3. The ancient atmosphere in both places are similar
  4. Fossil remains of the same land-dwelling animal were found on each continent
  1. Which of the following features is likely to form where two tectonic plates push toward each other?
  1. Ocean shorelineb. mountain range c. mid-ocean ranged. rift valleys
  1. One piece of evidence that supports the Theory of Plate Tectonics is found in the observation of rocks on either side of the Mid-Atlantic Ridge, shown in the picture provided.Plate Tectonic theory is supported because as you move out from the Mid-Atlantic Ridge, the rocks –
  1. have higher iron content
  2. become thicker and thicker
  3. are increasingly older
  4. are made of smaller particles
  1. Scientists theorized that the continents were once joined together even before they had modern evidence from rocks and fossils. Using only maps, they observed that –
  1. Continents with the most temperate climates were found near the Equator
  2. The oceans have become smaller throughout the history of the Earth
  3. The shapes of continents appeared to allow them to fit together
  4. Most of the larger land masses are in the Northern Hemisphere

  1. convergent b. divergentc. subduction zoned. transform
  1. What feature is most likely to occur between the South American plate and the African plate?
  1. Subduction zoneb. Trenchc. Mid-Ocean Ridged. Mountain
