3. The majority of the Earth’s mass makes up the: (A) mantle (B) Mohovosic discontinuity (C) core (D) crust (E) asthenosphere

4. The two kinds of crust are ______and ______: (A) Mohovosic discontinuity oceanic (B) Mohovisic discontinuity continental (C) continental mantle (D) oceanic mantle (E) continental oceanic

5. The ______separates the Earth’s crust and ______from rocks in the ______. (A) “Moho” lower mantle upper mantle (B) lower mantle upper mantle “Moho” (C) upper mantle “Moho” lower mantle (D) upper mantle lower mantle “Moho” (E) “Moho” upper mantle lower mantle

6. The Earth’s tectonic plates are composed of pieces of the: (A) crust (B) lithosphere (C) upper mantle (D) lower mantle (E) asthenosphere

7. The Earth’s tectonic plates float on top of the: (A) crust (B) lithosphere (C) upper mantle (D) lower mantle (E) asthenosphere

8. Less dense continental crust floats higher than more dense oceanic crust. This is an example of: (A) continental drift (B) tectonic plates (C) convection cells (D) isostasy (E) subduction

9. ______is the theory that states a super-continent named Pangea broke up into the modern continents. (A) continental drift (B) tectonic plates (C) convection cells (D) isostasy (E) subduction

10. Continental drift is caused by: (A) plate tectonics (B) isostasy (C) paleomagnetism (D) gravity (E) thermal convection

11. The study of magnetic particles on the bottom of the ocean floor is called: (A) isostasy (B) plate tectonics (C) paleomagnetism (D) thermal convection (E) sonar

12. An area of intense seafloor spreading is called: (A) San Andreas fault (B) Mid-Atlantic ridge (C) divergent rift (D) transform fault (E) convergent boundary

13. Two plates move away from each other at ______boundaries. (A) divergent (B) lateral (C) convergent (D) transform (E) isostatic

14. Two plates move toward each other ______boundaries. (A) divergent (B) lateral (C) convergent (D) transform (E) isostatic

15. Two plates slide parallel to each other at ______boundaries. (A) divergent (B) lateral (C) convergent (D) transform (E) isostatic

17. In some places two oceanic plates converge. One plate stays at the surface and the other plate dives down beneath it. This process is called: (A) convergence (B) subduction (C) divergence (D) transformation (E) rift formation

18. Sometimes down-going oceanic plates drag below continental plates. This forms: (A) mountains (B) rift valleys (C) deep ocean trenches (D) Mid-Atlantic ridges (E) suture zones
