Transcript

  • 1. Weathering and Erosion
  • 2. Weathering: break-up of rox from exposure to atmosphere • A)mechanical: break into smaller pieces w/o changing composition –frost action –plant growth –abrasion (rubbing)
  • 3. Frost Action
  • 4. Plant Growth
  • 5. B) Chemical weathering: rock changes into a different substance • Hydrolysis: rock reacts w/water –mica clay • Oxidation:reacts w/oxygen –-rust • carbonation: reacts w/carbon dioxide
  • 6. Oxidation
  • 7. Carbonation
  • 8. Carbonation: Acid Rain
  • 9. Karst Topography
  • 10. Karst Topography • Occurs in limestone bedrock • limestone easily weathers chemically (carbonation) by weak acids in groundwater • landforms created: –caverns –sinkholes –disappearing rivers
  • 11. Cavern
  • 12. Stalactites Stalagmites
  • 13. Sinkholes
  • 14. Weathering is a slow process • Fastest when –warm, wet climate –big temperature changes –steep slopes –little vegetation
  • 15. Erosion: movement of weathered material • Gravity • ice • water • wind
  • 16. Gravity: Landslide
  • 17. Gravity: Talus
  • 18. Water Erosion
  • 19. Water Erosion
  • 20. Wind Erosion
  • 21. Deposition:
