1. There are three types of stress related to the movement of plate boundaries. CONVERGENT DIVERGENT TRANSFORM COMPRESSION TENSION SHEAR

2. CONVERGENT PLATE BOUNDARY TRANSFORM FAULT PLATE BOUNDARY DIVERGENT PLATE BOUNDARY Three Types of Plate Boundaries

3. Processes that occur along the plate boundaries convergent plate boundaries

4. OBJECTIVES Explain the different processes that occur along the plate boundaries.   Enumerate other geologic activities formed in the three Convergent Crustal Plate

5. CONVERGENT PLATE BOUNDARY Convergence of different Types of Crustal Plates Oceanic vs. continental Oceanic vs. oceanic continental vs. continental

6. Oceanic - continental Convergent plate boundaries

7. Convergence between Oceanic Crustal Plate and Continental Crustal Plate

8. Since the mantle is hotter than the crust , the tendency of the subducted leading edge of the oceanic crust will be melted forming magma.

9. This allows the magma to rise and reach the edge of the continental crustal plate forming volcanic arc. water

10. Aside from volcanic arc, what other geologic events could be formed in convergence of oceanic-continental crustal plates? water

11. The continuous grinding of plates against each other will cause the occurrence of earthquake . water

12. One important geologic feature formed at the oceanic crust is TRENC H , also known as submarine valleys . water

13. Oceanic - Oceanic Convergent Plate Boundaries

14. A second type of convergent plate boundary involves the sinking of oceanic lithosphere beneath another plate of oceanic plate.

15. Converging oceanic plates will cause formation of trenches , and these trenches will become sources of earthquakes

16. The western half of the Pacific Ring of Fire is full of these volcanic island arcs, including Japan, Indonesia, and Philippines.

17. Oceanic crust Oceanic crust Many parts of the Philippines originated from oceanic-oceanic convergence. This resulted from the collision of two oceanic plates, with one of the plates diving under the other.

18. Continental-Continental Convergent Plate Boundaries

19. 1 Unlike the other two types of convergent boundaries, subduction ceases for this type of convergence.

20. Subduction ceases- no trench, no volcano and no island arc are created in this type of convergent plate boundary.

21. Instead it leads to the formation of large group of tall mountains called mountain range.

22. Most visible product of plate tectonics- HIMALAYAS. India Asia

23. Collision of continental plates is associated with shallow earthquake activities.

24. SUMMARY Three main types of Convergent Plate Boundary Convergence of Oceanic and Continental Crustal Plates Convergence OF TWO CONTINENTAL CRUSTAL PLATES Convergence of two Oceanic Crustal Plates

25. SUMMARY The convergence of Oceanic and Continental Crustal Plates can lead to the occurrence of Subduction zone that gives rise to the formation of volcanic arc , earthquakes , and trenches.

26. SUMMARY The convergence of Two Oceanic Crustal Plates can lead also to the occurrence of Subduction Zone that gives rise to the formation of volcanic island arc , earthquakes , and trenches .

27. SUMMARY If one of the leading edge of an oceanic plate suddenly flicks upward, it can generate Harbor Waves or known as Tsunami

28. SUMMARY The convergence of two Continental Crustal Plates differ from the other two types of convergent plate boundary because it ceases subduction zone, which means only mountain ranges and shallow earthquakes are created.
