Geography (Geomorphic Processes)

This Exam Covers the Following Topics

  1. Geomorphic Processes:
    • Interaction between exogenic and endogenic forces
    • Types of geomorphic agents (e.g., wind, water, glaciers)
    • Gradation (degradation and aggradation)
    • Dynamic equilibrium between forces shaping Earth’s surface
    • Tectonic activity and its influence on landforms
  2. Endogenic Processes:
    • Diastrophism (e.g., orogeny and epeirogeny)
    • Volcanism and tectonic activity
    • Role of geothermal energy in shaping landforms
    • Uplift and crustal movements
  3. Exogenic Processes:
    • Erosion and deposition
    • Weathering (chemical, physical, and biological)
    • Wind, water, glaciers as geomorphic agents
    • Transportation and deposition of materials
    • Landforms created by erosion (e.g., valleys, dunes, deltas)
    • Mass wasting processes (e.g., landslides, creep, slumping)
  4. Weathering:
    • Chemical weathering (hydration, oxidation, carbonation)
    • Physical weathering (frost action, thermal expansion, exfoliation)
    • Biological weathering (root wedging, burrowing organisms)
    • Factors influencing the rate of weathering
  5. Mass Movements:
    • Creep, rock falls, landslides, debris avalanches, solifluction
    • Factors contributing to mass movements (e.g., heavy rainfall, vegetation)
    • Influence of climate and tectonics on mass movements
  6. Soil Formation:
    • Factors affecting soil formation (parent material, topography, climate, biological activity, time)
    • Processes like eluviation, leaching, infiltration
    • Influence of weathering on soil profiles
    • Role of vegetation and organic matter in soil development
  7. Karst Topography:
    • Carbonation and the formation of karst landscapes
    • Development of caves, sinkholes, and other karst features
  8. Human Impact on Geomorphic Processes:
    • Effects of deforestation, construction, and agriculture on geomorphic processes
    • Accelerated erosion and mass movements due to human activity
  9. Climatic Influences on Geomorphic Processes:
    • Impact of polar, temperate, and tropical climates on weathering, erosion, and deposition
    • Role of glaciers, wind, and running water in different climatic regions
  10. Landforms and Landscape Evolution:
    • Formation of U-shaped and V-shaped valleys
    • Alluvial fans, deltas, and floodplains
    • Cirques, moraines, and glacial landforms
