1. Lecture-9 1 Lecture #09- Transform Boundaries

2. Lecture-9 2 Transform Boundaries F Not all plate boundaries are convergent or divergent; many are defined by lateral relative movement F These types of plate boundaries are called transform boundaries F Here material is not being created (as it is at ridges) and is not being buried (as it is as subduction zones)

3. Lecture-9 3

4. Lecture-9 4 Transform Boundaries F Since no material is being created or destroyed transform boundaries are also referred to as conservative boundaries F Another name is a strike-slip boundary F What is the prime example of a conservative plate boundary in the Saudi Arabia?

7. Lecture-9 7 Transform Boundaries F Transform faults occur most often as connecting segments between spreading ridges

10. Lecture-9 10 Lava Lake “Transform Fault”

11. Lecture-9 11 The most famous transform fault in the world – the San Andreas. What is an example of another major transform boundary?

12. Lecture-9 12 The North Anatolian Fault System (Microplate ) (does not connect spreading ridges)

13. Lecture-9 13

14. Lecture-9 14 Transform Boundaries, Summary F Transform boundaries represent lateral movement between plates F Material is neither created or destroyed, but rather conserved F Most transform faults connect divergent plate boundaries (MOR), but not all

15. Lecture-9 15 Transform Boundaries, Summary F Like divergent and convergent plate boundaries there is significant seismicity associated with transform faults (earthquakes) F Unlike the other types of boundaries there is relatively little volcanism
