PLATE TECTONICS

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

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.
