Plate Tectonics
Across
- 4. These occur at transform boundary faults and can cause tremendous devastation
- 5. Layer of Earth with the lowest temperature
- 6. When one tectonic plate moves underneath another one, it’s called this
- 7. Type of plate boundary where two plates collide
- 9. Earth’s thickest layer
- 11. Theory that the lithosphere is divided into tectonic plates that move on the asthenosphere
- 12. The bending and crumpling of rock. This happens at continental vs. continental convergent boundaries and results in the tallest mountains
- 14. This is the process of creating new oceanic crust
- 15. Theory that the continents were once joined as one large, single land mass
- 17. Word used to describe the state of the mantle
- 18. Type of plate boundary where two plates separate or move apart
Down
- 1. Scientist that proposed Earth’s continents were once joined together in a single land mass
- 2. The process of plates sliding past each other in opposite directions. This can be found at transform boundaries and results in faults.
- 3. Layer of Earth that is composed of Fe & Ni and is solid
- 5. Type of crust that is thick and contains granite
- 7. This is a type of heat transfer (hint: lava lamp). Some scientists believe these are occurring in the mantle and moving the tectonic plates
- 8. Areas along a transform boundary created by the shearing of two pieces of crust. There is a famous one in California
- 10. This forms on land at divergent plate boundaries. There is a great one in eastern Africa
- 13. These form under water (on the ocean floor) at most convergent boundaries
- 16. Layer of Earth that is composed of Fe & Ni and is liquid
