Earthquake Test Review
If the boldface word makes the sentence true, write “TRUE“ in the space provided. If the boldface word makes the
sentence false, write the correct term in the space provided.
(chapter 15 in the Blue Glencoe book)
___________________ 1. The theory of plate tectonics suggests that Earth’s crust is broken into
sections called plates.
____________________2. The uppermost portion of the mantle is liquid.
____________________3. The lower portion of the crust and the upper portion of the mantle is
called the core.
____________________4. Below the lithosphere lies the asthenosphere.
____________________5. Earths layers are like rafts floating on the asthenosphere.
____________________6. At a divergent boundary, plates are being forced together.
____________________7. At a transform fault boundary, plates move past each other.
____________________8. New crust is added at divergent boundaries.
____________________9. An ocean crustal plate rises at a convergent boundary with a continental plate.
____________________10. A trench forms at the boundary between an ocean plate and a continental
plate.
____________________11. Ocean crust sinks under continental crust because ocean crust is less dense.
____________________12. Crustal material can be destroyed at a divergent boundary.
____________________13. When two plates containing continental crust collide, mountains are formed.
____________________14. The motion of Earth’s plates is caused by heat.
____________________15. Cooling of the asthenosphere causes its material to be forced toward the
surface
____________________16. Two plates sliding past one another in opposite directions form a divergent
boundary.
____________________17. A convection current is the cycle of cooler rock sinking and forcing
warmer rock to rise.
____________________18. A shift is a line along which rocks or rock formations move.
____________________19.Africa may split into two landmasses at the Great Rift Valley.
