Study Notes
Geomorphic Processes: Shaping the Earth
- Geomorphic processes are natural forces that alter landforms on Earth. They involve material movement from various forces like gravity, wind, water, and ice.
Types of Geomorphic Processes
- Classified into Endogenic (internal) and Exogenic (external) processes.
Endogenic (Internal) Processes
- Caused by forces from the Earth's interior.
- Diastrophic Processes: Cause large-scale crustal deformation (mountain building and continent uplift).
- Epeirogenic Movements: Vertical uplift or subsidence of large landmasses.
- Orogenic Movements: Folding and faulting of the crust due to tectonic forces, creating mountains.
- Volcanism: Magma, gases, and ash eruption onto the surface, making volcanic landforms.
- Seismic Activity (Earthquakes): Sudden fault movements creating rift valleys, tsunamis, and changing landforms.
Exogenic (External) Processes
- Caused by external forces like wind, water, and ice.
- Weathering: Breakdown of rocks into smaller pieces.
- Physical Weathering: Freeze-thaw, exfoliation (peeling).
- Chemical Weathering: Oxidation, carbonation.
- Biological Weathering: Root penetration, lichen growth.
- Erosion and Deposition: Movement and accumulation of sediment.
- Fluvial Processes (Water): River erosion (abrasion, attrition, solution) and deposition (deltas, floodplains, valleys).
- Aeolian Processes (Wind): Wind erosion (sand dunes, loess deposits, desert pavements).
- Glacial Processes (Ice): Ice movement (U-shaped valleys, moraines, fjords).
- Coastal Processes (Waves): Cliff, beach, and spit formation from erosion and deposition.
- Mass Wasting: Downhill movement of materials due to gravity (landslides, rockfalls, soil creep).
- Weathering: Breakdown of rocks into smaller pieces.
