1. Class 8a: Weathering and mass wasting

2. Gradational processes 1.Weathering 2.Mass wasting 3.Erosion/deposition

3. Weathering Weathering: breaking down of rock

4. Weathering Speed of weathering? Bedrock: Climate: Vegetation: Steepness and orientation of slope

5. Mechanical weathering Mechanical weathering breaks rocks into smaller pieces

6. Chemical weathering Changes the chemistry of rocks

7. Karst

8. Karst: caves and caverns

9. Karst: aboveground formations

10. Mass wasting Downward movement of material due to gravity

11. Mass wasting: creep Creep: nearly imperceptible movement

12. Mass wasting: flow Flow: High moisture content

13. Mass wasting: slide Slide: Sudden movement of non- saturated material

14. Mass wasting: slide Three landscape consequences:

15. Mass wasting: fall Fall: Rock goes airborne

16. Erosion and deposition Erosion: Transport: Deposition:

17. Aeolian processes Aeolian: related to wind

18. Deflation and abrasion Deflation: removal and lifting of particles Abrasion: sandblasting or polishing

19. Aeolian transport

20. Aeolian deposition
