1. Erosion and Deposition

2. Breaking Down Processes Weathering breaking down The breaking down of the earth’s material by natural processes. Erosion moved The process by which weathered rock and soil particles are moved from place to place. Deposition laid down The process by which weathered sediments are laid down in a new location creating new landforms.

3. 5 Agents of Erosion Gravity Glaciers Wind Surface Water / Running Water Ocean Shoreline / Ocean Waves

4. Gravity Pulls Pulls rock and soil down a slope Mass Movement Called Mass Movement Rapid Rockslides Mudflow Avalanche

6. Gravity Slow Slump Creep

7. Mass Wasting

8. Glaciers largesmall Carry very large to very small debris Most powerful agent Deposits moraines Form piles called moraines Drumlins – little mounds Glacial lakes Kettle lakes U-shaped valleys

14. Wind loose Removes loose material from the earth’s surface. wind speed Amount of material carried depends on wind speed deserts Most active in deserts, plowed fields, beaches Deposits by wind Loess- Loess- layer of fine silt or sand Dunes- Dunes- mounds of sand

17. Wind Erosion

18. Running Water MAJOR CAUSE OF EROSION load When water moves it carries particle called the load. Speed Speed of water determines the size of the load canyons Creates canyons and valleys River deposits Delta Oxbow Oxbow lake Flood plains

19. River deltas

20. Oxbow Lakes

21. Flood Plains

22. Waves shape Constantly erode and shape the shoreline. Formation Sea cliffs stacks Sea stacks and caves
