  1. Topic 4 Weathering, Erosion , & DepositionDR. FULE RA.

  2. Erosion • Erosion is the removal of rock particles from a location. • Caused by water, wind, ice, or gravity.

  3. DISCUSS with your table: • What is the connection between weathering and erosion?? • Why did we learn weathering first?? • How does this affect the Earth? Us?

  4. Add to your notes! • DESCRIPTION: • The movement of rock particles from a specific location EROSION:

  5. Add to your notes! • CAUSED BY: • WATER • WIND • ICE • GRAVITY EROSION

  6. WATER EROSION Water sources such as rivers, streams, ocean tides, and runoff can move rock particles away....

  7. Water Erosion-Rivers • Rivers and streams carry sediment. As the sediment moves mechanical weathering occurs. • Through water erosion, rivers create waterfalls, flood plains, and valleys.

  8. Water Erosion-Waves • Waves- waves shape the coasts by transporting sand. While the sand is moved, mechanical weathering occurs. • Waves create sea stacks, caves, arch, and wave-cut cliffs.

  9. Erosion by Runoff • As water from precipitation (rain, snow, etc.) moves over the land, it carries particles with it. The moving water is called runoff. • Runoff creates rills and gullies.

  10. WIND EROSION Sometimes the wind can move rock particles away: this can lead to dust storms!

  11. Wind Erosion creates dust storms, hoodoos, and arches. WIND EROSION

  12. Ice Erosion As a glacier flows over the land, it picks up rocks in a process called plucking.

  13. Ice erosion creates: U-shaped valleys, glacial lakes, moraines, drumlins, and kettle lakes. Ice Erosion

  14. Ice erosion creates: U-shaped valleys, glacial lakes, moraines, drumlins, and kettle lakes. Ice Erosion

  15. Think about it…. • Water is NEEDED by all living things to survive. • How does water change the planet?

  16. Erosion by Gravity • Gravity causes sediment to move downhill. • It creates: landslides, mudflows, and creeps.

  17. Analyze your learning… Compare the relationship between weathering and erosion to the relationship between convergent and divergent boundaries.

  18. Rate your learning…. • Where are you on the generic learning scale (0-4) with: • Understanding erosion? • The difference between weathering and erosion? • Understanding how weathering and erosion work together?

  19. Weathering and Erosion work together continuously to wear down and carry away the rocks at the Earth’s surface!!!!! END - Erosion

  20. Deposition • Deposition is the process in which sediment laid down in new locations. • Caused by water, wind, ice, and gravity.

  21. Think about it… • What needs to happen before deposition can occur? • Why did we study deposition last in our weather, erosion, & deposition mini unit?

  22. Add to your notes! Deposition: Deposition is the process in which sediment is put down in new locations. Deposition:

  23. Add to your notes! • CAUSED BY: • water • wind • ice • gravity Deposition
