PLATE TECTONICS STUDY GUIDE! KEY TERMS: Write the letter of the correct answer on the line. 1. _____ Solid, inner most layer of the Earth. A. Lithosphere 2. _____ When a solid has the ability to flow. B. Divergent Boundary 3. _____ Thin outermost layer of the Earth. C. Plate Tectonics 4. _____ A crack in the Earth’s surface. D. fold 5. _____ Process when the oceanic plates slide under continental plate. E. Crust 6. _____ Top most solid part of earth made of crust and mantle. F. Pangaea 7. _____ The boundary between mantle and outer layer. G. Moho 8. _____ When tectonic plates collide into eachother. H. Convergent Boundary 9. _____ When tectonic plates slide past each other. I. Transform Boundary 10. _____ Layer of the Earth from the crust to the core. J. Mantle 11. _____ A soft layer of the mantel on which pieces of the lithosphere move. K. Asthenosphere 12. _____ A bend in a rock. L. Fault 13. _____ Place where sea-floor spreading takes place. M. subduction 14. _____ Scientist who proposed the Theory of Plate Tectonics N. Inner Core 15. _____ Theory that explains the movement of the lithosphere plates. O. Alfred Wegener 16. _____ Single giant land mass, which broke into large pieces P. Plasticity and drifted apart. 13._____ Tectonic plates move away from each other. Q. Mid-Ocean Ridge R. Rifting 14. The movement of the ocean floor on either side of a mid-ocean ridge. FILL IN THE BLANKS: Which part of the Earth’s layers is filled with iron and probably responsible for the magnetic field? ____________________. What layer has life on earth? __________________. Where is the Moho located?______________________________________________________. The Moho has plasticity, which allows the crust to move slowly over the mantle. What does plasticity mean? _____________________________________________________________________________. Describe each of the following plate boundaries and how they move: CONVERGENT: _____________________________________________________________ DIVERGENT:_______________________________________________________________ TRANSFORM:______________________________________________________________ Describe the three types of stress: COMPRESSION:___________________________________________________________________. SHEAR:__________________________________________________________________________. TENSION:________________________________________________________________________. True or False: If false write the correct answer. _______ Tectonic plates are located within the mantle. _______________________________________________________________________________. ________ The lithosphere contains two types of crust, oceanic and continental. ________________________________________________________________________________. _________. Earth’s continental crust is thicker and denser than oceanic crust. ________________________________________________________________________________. ________ There are 7 tectonic plates that the lithosphere is divided into. _________________________________________________________________________________. Find where we live! What are the three plates closest to our home? 1._________________________ 2._____________________ 3.____________________ List three types of evidence/clues Alfred Wegener used to develop his theory of Pangea (Hint: Notes, page 6): 1.______________________________ 2.______________________________ 3.______________________________
