Topics in Exogenetic Processes Part-2
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
