4. Plate Boundaries Key Questions 1. What are the features at a convergent boundary? 2. What are the features at a divergent boundary? 3. What are the features at a transform boundary?

5. Convergent Plate Boundary 1.Oceanic-Oceanic 2.Continental- Continental 3.Continental- Oceanic Features: Mountains Trenches Volcanoes

6. Continental-Oceanic Convergent Boundary More dense Oceanic plate subducts (slides) below the Continental plate. Features: oTrenches oVolcanoes oMountains

7. Oceanic-Oceanic Convergent Boundary Subduction of the older more dense Oceanic Plate Forms a trench or volcanic islands

8. Continental-Continental The plates buckle up and forms mountain ranges.

9. Features of Divergent Boundary: Mid-Ocean Ridge Rift Valleys Volcanoes

10. Transform Boundaries Earthquakes occur at transform boundaries.

11. World’s Largest Earthquake 9.5 Magnitude, Chile 1960

12. World’s Largest Earthquake 9.5 Magnitude Southern Chile 1960 Estimated 5,700 killed 3,000 injured 717 initially missing from Chile 2,000,000 people left homeless 58,622 houses completely destroyed
