9. ____________ IS THE THEORY THAT THE PLATES WERE ONCE CONNECTED BUT HAVE SINCE DRIFTED APART A. Cold Fussion B. Quantum Physics C. Continental Drift D. Big Bang

10. IF THE LAYERS OF THE EARTH WERE MADE OF ALCOHOL, WATER, AND MOLASSES, THE CORE OF THE EARTH WOULD BE A. water vapor B. water C. alcohol D. molasses

11. WHICH FACTOR DETERMINES THE ARRANGEMENT OF THE EARTH’S LAYERS? A. the temperature of the layers B. the density of the layers C. the pressure of the layers D. the mass of the layers

12. WHICH OF THE FOLLOWING STATEMENTS IS TRUE ABOUT THE INTERACTIONS OF CRUSTAL PLATES? A. Oceanic crust is denser than continental crust and will subduct under the continental crust. B. Continental crust is denser than oceanic crust and will subduct under the oceanic crust. C. Oceanic crusts produce mountains when they collide with one another. D. When continental crusts collide both are subducted and crust is destroyed.

13. IN WHICH OF EARTH’S LAYERS DO CONVECTION CURRENTS OCCUR? A. crust B. core C. mantle D. lithosphere

14. 10. WHY DO VOLCANOES AND EARTHQUAKES OCCUR FREQUENTLY IN SOME PARTS OF THE EARTH, BUT RARELY OR NEVER IN OTHER PARTS? A. Volcanoes and earthquakes result from interactions at plate boundaries. B. Volcanoes and earthquakes are caused by global warming. C. Volcanoes and earthquakes are caused by reversal of Earth’s gravitational poles. D. Volcanoes are caused by earthquakes, so they always occur at the same ocation.

16. 8. WHICH OF THE FOLLOWING STATEMENTS IS TRUE ABOUT MAGMA PARTICLES IN THE EARTH’S MANTLE? A. The magma closest to the surface gains kinetic energy and therefore becomes more dense. B. The magma closest to the surface gains kinetic energy and therefore becomes less dense. C. The magma closest to the core gains kinetic energy and therefore becomes more dense. D. The magma closest to the core gains kinetic energy and therefore becomes less dense.

17. WHICH OF THE FOLLOWING IS NOT A CONSEQUENCE OF TECTONIC PLATE CONVERGENCE? A. Earthquakes B. Volcanoes C. Production of new crust D. Mountains
