1. Plate Boundaries Lithospheric Plates are pushed and pulled around by the underlying convection cells in the upper mantle (Asthenosphere).

2. What is a plate boundary and what happens at plate boundaries? ARABIAN PLATE INDIAN PLATE SCOTIA PLATE

3. What is a plate boundary and what happens at plate boundaries?

4. Convergent Divergent Transform 3 types of plate boundaries

5. Convergent Boundaries Convergent plate boundaries are locations where lithospheric plates are moving towards one another.

6. Divergent plate boundaries are locations where plates are moving away from one another. This occurs above rising convection currents. As plates move apart new material is erupted to fill the gap Divergent plate boundaries are locations where plates are moving away from one another. This occurs above rising convection currents. As plates move apart new material is erupted to fill the gap Divergent Boundaries

7. Plates slide past each other laterally. Transform Boundaries

10. There are 3 types: -Ocean – Ocean (O-O) -Ocean – Continental(O-C) -Continental – Continental (C-C) There are 3 types: -Ocean – Ocean (O-O) -Ocean – Continental(O-C) -Continental – Continental (C-C) Convergent Boundary Types

11. When two oceanic plates collide, one runs over the other which causes it to sink into the mantle forming a subduction zone. The subducting plate is bent downward to form a very deep depression in the ocean floor called a trench. The worlds deepest parts of the ocean are found along trenches.

12. O-C Convergent Boundary Oceanic plate subducts underneath the continental plate Oceanic lithosphere heats and dehydrates as it subsides The melt rises forming volcanoes Oceanic plate subducts underneath the continental plate Oceanic lithosphere heats and dehydrates as it subsides The melt rises forming volcanoes

13. Continental plates collide with other continental plates and pushes up tall mountains C-C Convergent Boundary

15. Courtesy of www.ngdc.noaa.gov Can you locate where the plates are diverging? Where they are coming apart, a mid-ocean ridge forms. Can you locate where the plates are diverging? Where they are coming apart, a mid-ocean ridge forms. O-O Divergent Boundary

16. C-C Divergent Boundary Iceland has a divergent plate boundary running through its middle called a rift valley

19. O-O Transform Boundary Most transform faults are found in the ocean basin and connect offsets in the mid-ocean ridges.
