Plate Tectonics Crossword Puzzle
Across
- 2. Scientists study these in order to learn about the interior of the earth.
- 7. These are formed under water at divergent plate boundaries. They are areas where new ocean crust is formed.
- 8. Layer of earth that is composed of Fe & Ni and is solid.
- 10. Theory that the continents were once as one large, single land mass.
- 14. These form under water (on the ocean floor) at most convergent boundaries.
- 17. This is a type of heat transfer (hint: lava lamp). Some scientist believe these are occurring in the mantle and moving the tectonic plates.
- 18. Earths thickest layer.
- 19. This forms on land at divergent plate boundaries. There is a great one in Eastern Africa.
- 21. Type of plate boundary where two plates collide.
- 23. Type of plate boundary where two plates slide past each other in opposite directions.
- 24. Scientist that proposed Earth's continents were once joined together in one single land mass
Down
- 1. These occur at transform boundary faults and can cause tremendous devastation.
- 2. When one tectonic plate moves underneath another one, it's called this.
- 3. The name of the supercontinent that existed 245 million years ago.
- 4. Word used to describe the state of the mantle.
- 5. Type of plate boundary where two plates separate or move apart.
- 6. The cool, outermost layer of Earth that consists of the crust and uppermost part of the mantle.
- 9. Type of crust that is thinner and contains basalt.
- 11. The bending and crumpling of rock. This happens at continental vs. continental convergent boundaries and results in the tallest mountains.
- 12. The process of plates sliding past each other in opposite directions. This can be found at transform boundaries and results in faults.
- 13. The layer just below the lithosphere.
- 15. Layer of earth with the lowest temperature.
- 16. This is the process of creating new oceanic crust.
- 17. Type of crust that is thick and contains granite.
- 20. Areas along the transform boundary created by the shearing of two pieces of crust. There is a famous one in California.
- 22. Layer of earth that is composed of Fe & Ni and is liquid.
