PLATE TECTONICS
Across
- 1. deep rift valley formed by the divergent boundary, extending the length of the mid-ocean ridge and the site of frequent volcanic activity
- 3. process that occurs at mid-ocean ridges where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.
- 4. hemispheric-scale long but narrow topographic depressions of the seafloor.
- 5. the result of a sudden release of energy in the earth's crust that creates seismic waves.
- 6. a type of fault whose reelative motion is predominantly horizontal on either sinistral or dextral direction.
- 9. pieces of the earth's crust and uppermost mantle, together referred as the lithosphere.
- 10. an actively deforming region where two or more tectonic plates or fragments of the lithosphere move toward one another and collide.
- 11. the collective and concerted movements of groups or aggregates of molecules within fluids and rheids ,either through advection or through diffusion or as a combination of both of them.
- 13. movement of the earth's continents relative to each other, thus appearing to drift across the ocean bed
Down
- 2. a scientific theory that describes the large-scale motion of earth's lithosphere.
- 4. a series of water waves caused by the displacement of a large volume of a body of water, generally an ocean or a large lake.
- 7. process that takes place at convergent boundaries by which one tectonic plate moves under another tectonic plate and sinks into the mantle as the plates converge.
- 8. at the locations where two tectonic plates interact, a boundary between these plates exist.
- 12. a linear feature that exists between two tectonic plates that are moving away from each other.
