Key Topics to Revise

1

Work of Rivers and Landforms

  • Rivers form when multiple water flows combine and flow according to gravity along slopes
  • River work depends on: slope of land, rock type, water volume, flow length, and sediment volume
  • Erosional landforms: Gorges (canyons), V-shaped valleys, waterfalls - formed in upper course due to high speed
2

Work of Glaciers and Landforms

  • Glaciers form in regions with temperatures below freezing point through snow accumulation
  • Glacier movement: 1 cm to 1 m daily (Jacobshavn Glacier in Greenland moves 46 m/day)
  • Erosional landforms: Cirques (bowl-shaped depressions), Arêtes (knife-edge ridges), Horns (pyramid peaks), U-shaped valleys, Hanging valleys, Rôche moutonnées
3

Work of Wind and Landforms

  • Wind erosion is prominent in deserts and semi-arid regions due to lack of vegetation
  • Mechanical weathering creates abundant loose material for wind transport
  • Erosional landforms: Mushroom rocks, Deflation hollows, Yardangs
4

Work of Sea Waves and Landforms

  • Sea waves are created by winds and tides, carry out erosion, transportation, and deposition
  • Wave energy depends on wind speed, fetch (distance over water), and water depth
  • Erosional landforms: Wave-cut platforms, Sea caves, Sea arches, Sea cliffs
