glaciers

• Glacial erosion processes


  • Plucking
  • Abrasion
  • Freeze-thaw weathering
• Glacier movement


  1. Ice formation

  2. Increased weight causes downward movement

  3. Uneven movement causes cracks

  4. Meltwater forms

  5. Glacier moves over meltwater

  6. Erosion of surface

  7. Glacier melts and deposits debris
• Landforms from glacial erosion

  • Cirques
  • Knife edge ridges
  • Pyramid peaks
  • Truncated spurs
  • Glacial troughs
  • Hanging valleys
• Landforms from glacial deposition

  • Rock debris
  • Erratic boulders
  • Drumlins
• Opportunities in glacial areas

  • Tourism
  • Grazing
  • Crop farming
  • Conifer forestry
  • Quarrying
• Conflicts in glacial areas include pollution from quarrying affecting tourism, high house prices preventing local access, and damage to farmland from tourism
• In the Lake District, measures like park and ride, transport hubs, and traffic calming have been implemented to manage tourism impacts
• In the Isle of Arran, tourism has brought new jobs and infrastructure but also increased injuries/fatalities, erosion, and traffic
