Plate Tectonics Puzzle

Plate Tectonics Crossword Puzzle 1. Type of plate boundary where two plates separate or Divergent move apart. 2. These form under water (on the ocean floor) at most Trenches convergent boundaries. 3. The process of plates sliding past each other in oppo- Shearing site directions. This can be found at transform boundaries and results in faults. 4. Word used to describe the state of the mantle. Plasticity 5. Areas along the transform boundary created by the Faults shearing of two pieces of crust. There is a famous one in California. 6. This forms on land at divergent plate boundaries. There is a great one in Eastern Africa. Rift Valley 7. This is a type of heat transfer (hint: lava lamp). Some Convection Curscientist believe these are occurring in the mantle and rents moving the tectonic plates. 8. Layer of earth that is composed of Fe & Ni and is liquid. Outer Core 9. Earths thickest layer. Mantle 10. These occur at transform boundary faults and can cause tremendous devastation. Earthquakes 11. Theory that the continents were once as one large, single land mass. Continental Drift 12. These are formed under water at divergent plate Plate Tectonics boundaries. They are areas where new ocean crust is formed. 13. Type of crust that is thick and contains granite. 1/2 Continental 14. Type of plate boundary where two plates collide. Convergent 15. Scientist that proposed Earth's continents were once Wegener joined together in one single land mass 16. The bending and crumpling of rock. This happens Folding at continental vs. continental convergent boundaries and results in the tallest mountains. 17. Layer of earth with the lowest temperature. Crust 18. This is the process of creating new oceanic crust. Sea Floor Spreading 19. Layer of earth that is composed of Fe & Ni and is solid. Inner Core 20. When one tectonic plate moves underneath another Subduction one, it's called this. 21. Theory that the lithosphere is divided into tectonic plates that move on the asthenosphere. Plate Tectonics 22. The name of the supercontinent that existed 245 mil- Pangaea lion years ago. 23. The layer just below the lithosphere. Asthenosphere 24. The cool, outermost layer of Earth that consists of the Lithosphere crust and uppermost part of the mantle. 25. Type of crust that is thinner and contains basalt. Oceanic 26. Scientists study these in order to learn about the in- Seismic Waves terior of the earth. 27. Type of plate boundary where two plates slide past each other in opposite directions. 2/2 Transform
