Geomorphology and the Earth
Geomorphic processes, weathering and mass movement
Practise 2 PYQsConcepts to cover
- Endogenic and exogenic forces; gradation, degradation and aggradation
- Diastrophism: orogenic and epeirogenic movements, earthquakes and volcanism as endogenic processes
- Physical weathering: unloading, thermal expansion, frost wedging, salt weathering, exfoliation
- Chemical weathering: solution, carbonation, hydration, oxidation and reduction; rain water as agent
- Biological weathering and the role of climate in weathering
- Mass movements: slow (creep, solifluction), rapid (earthflow, mudflow, debris avalanche), landslides
- Erosion, transportation and deposition by geomorphic agents
- Significance of weathering: soil formation, enrichment of ores, biomes
