Across
- 4. raise up (strata, mountains, etc.) by an upward movement of the earth’s crust.
- 10. created when tectonic plates slide past each other horizontally along strike-slip faults or transform faults
- 15. For the Earth, it is the crust
- 17. elevated region on an ocean floor at the boundary between two diverging tectonic plates where new crust forms from upwelling magma.
- 18. where two plates are moving away from each other and new crust is forming.
- 19. a large, flat block of solid rock that floats in the lithosphere.
Down
- 1. The location where two plates meet.
- 2. when lava and gas are released from a volcano—sometimes explosively
- 3. a process in which new ocean floor is created as molten material from the earth's mantle rises in margins between plates or ridges and spreads out.
- 5. a sudden, violent shaking on the ground caused by tectonic plates,
- 6. Long, narrow depression on the seafloor that forms at the boundary of tectonic plates where one plate is pushed, or subducts, beneath another
- 7. When plates move towards each other and may collide
- 8. a geological process in which the oceanic lithosphere is recycled into the Earth's mantle at convergent boundaries.
- 9. zone of seismic and volcanic activity that coincides in general with the margins of the Pacific Plate.
- 11. A theory proposed by Alfred Wegener.
- 12. The Earth’s layer that tectonic plates float on.
- 13. a surface or shape that is or would be exposed by making a straight cut through something, especially at right angles to an axis.
- 14. Examine methodically and in detail the constitution or structure of, typically for purposes of explanation and interpretation.
- 16. the speed at which something happens or changes, or the amount or number of times it happens.
