1. IntroIntro Objective 12/06/11 Explain how landforms are created through erosional processes How is erosion different from weathering?

2. EROSIONAL LANDFORMS

3. Erosional Landforms  Erosion  A gravity driven process that moves solids (sediment, soil, rock and other particles) from their source and deposits them elsewhere.

5. Erosional Landforms  What causes erosion?  Mostly water and wind  Rain, snow, sleet  Ice, glaciers  Rivers, streams  Ocean waves

6. Erosional Landforms  Rain, snow, sleet (weather)  Dissolves rock, freezes and expands rock, or washes rock away

7. Erosional Landforms  Ice, glaciers  Sediment picked up into the glacier and carried

8. Erosional Landforms  Rivers & Streams  Cut through the landscape, move rock from one place to another

9. Erosional Landforms  Ocean Waves  Erode the shorelines of the land with power and force

10. Erosional Landforms  Shoreline Erosional Landforms  Headlands  Sea Cave  Sea Arches  Sea Stacks  Wave Cut Terrence  Beaches

11. Headlands

12. Sea Caves

13. Sea Arches

14. Sea-Stacks

15. Wave-cut Terraces

16. Beaches

17. Erosional Landforms  What happens to eroded rock?  Rock that is eroded is carried towards the ocean as sediment  Becomes sand  Becomes deltas  Becomes sea-bed

18. Erosional Landforms  Ways to stop sand movement:  Groins  Jetties  Breakwaters

19. Erosional Landforms (Groins)

20. Erosional Landforms (Jetties)

21. Erosional Landforms (Breakwaters)

22. Erosional Landforms  Summary:  What is erosion?  What causes erosion?  What are some shoreline erosional landforms?  What are some ways to stop our shorelines from eroding away?

23. Objective 12/06/09 OutroOutro Explain how landforms are created through erosional processes. Using a Flow-Map, show how headlands can eventually become beaches.
