Across
  1. 3. A fault on which the two blocks slide past one another.
  2. 4. A type of plate movement that found in San Andreas Fault.
  3. 8. This boundary occurs when two plates move away.
  4. 10. Occurs when two plates move toward each other.
  5. 11. linear, strata normally dip away from axial center, oldest
  6. 12. The term for the force exerted by a tectonic plate descending into the mantle.
  7. 14. They are geological features formed by convergent boundaries.
  8. 16. Opposite of a convergent boundary, a divergent boundary is formed by the spreading of a tectonic plate.
  9. 17. It occurs between the core and mantle or even between the asthenosphere and lithosphere.
  10. 18. It is formed at the base of the continental rise about 4000 to 6000 meters deep.
Down
  1. 1. The one who proposed that the sea floor is spreading.
  2. 2. These are inclined fractures where the blocks have mostly shifted vertically.
  3. 5. Gravitational force that causes a plate to move away from the crest of an ocean ridge, and into a subduction zone.
  4. 6. It is a fracture or zone of fractures between two blocks of rock.
  5. 7. These are regions that are below sea level and about 70% of these areas hold the planet’s water.
  6. 9. Internal process drives the molten rocks in the mantle to rise to the lithosphere.
  7. 10. A fault rock which is cohesive with a poorly developed or absent planar fabric, or which is incohesive, characterized.
  8. 12. It is the force per unit that place on a rock.
  9. 13. Another geological feature that results from a subduction zone.
  10. 15. It is a central valley formed at the summit of the oceanic ridges as the molten materials continuously flow out from the ridges.
