7. What is Transform Fault Boundary? - two plates slide past one another where the motion is predominantly horizontal. - the fracture zone that forms a transform plate boundary is known as transform fault. - natural or human-made structures that cross a transform boundary are offset-split into pieces and carried in opposite directions.

8. most of the transform faults are found in the ocean basin, few in the continental crust it is a conservative type boundary , no lithosphere is created nor destroyed, instead, rocks are displaced, pulverized along shearing zones as the plates grind, creating linear fault valley or undersea canyon.

9. At shearing zones - shallow earthquakes happen frequently - massive rocks are torn apart and displaced tens to hundred miles away along this area

10. 3 types of Transform Plate Boundary

11. Ridge-ridge boundaries Trench-trench boundaries Ridge-trench boundaries

12. RIDGE-RIDGE - Transform faults that offset mid-oceanic ridges , transfer spreading from one segment of the ridge to the next.

13. RIDGE-TRENCH - transform faults can also occur between a spreading center and a  subduction zone  (ridge-trench or ridge-arc arc transform ). - a transform fault that connects spreading center to deep -sea trenches in subduction zones.

14. TRENCH-trench - Transform faults can also occur between two subduction zones (trench-trench or arc-arc transforms)

15. Other classification Oceanic-oceanic Continental-continental

16. Oceanic-oceanic

17. Virgin Islands National Park is a sheared-up landscape forming as the Carribean plate slides eastward past the oceanic part of North American Plate

18. Continental-continental

19. Responsible not only for destructive earthquakes but also for the spectacular scenery of the San Francisco Bay area and other coastal regions of California

20. Transform fault boundary between Pacific Plate and Indo-Australian PLate
