9. 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

10. - 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.

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

12. 3 types of
Transform Plate
Boundary

13. 1. Ridge-ridge
boundaries
2. Trench-trench
boundaries
3. Ridge-trench

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

18. 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.

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

23. Other classification
1.Oceanic-oceanic
2.Continental-
continental

24. Oceanic-oceanic

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

26. Continental-continental

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

29. Transform fault boundary between Pacific Plate and
