A-Level Landforms in the Tropics (Cluster 2)

how geomorphic processes and human activity mould fluvial and karst landforms across the humid tropics

What the syllabus expects

• Weathering processes split into chemical types (carbonation, hydrolysis, oxidation, reduction, solution) and physical types (thermal weathering, salt weathering, freeze-thaw, pressure release)
• Both natural and human factors affect how rocks weather
• Material moves down slopes through mass movement (fall, flow, creep, slide) and water erosion (rainwash, rillwash and splash erosion)
• Natural and human factors both influence the movement of material on slopes
• Fluvial processes comprise deposition alongside erosion (cavitation, corrasion, corrosion) and transportation (saltation, solution, suspension, traction)
• Natural and human factors both shape fluvial processes
• Karst landforms found in the humid tropics include cockpit karsts, tower karsts and caves
• Cockpit karsts are marked by cone-shaped hills and star-shaped depressions
• Tower karsts feature towers rising from plains
• Caves feature solutional openings and speleothems
• The part geomorphic processes play in forming karst landforms
• The factors that shape how karst landforms form
• The ecosystem services that karst landforms provide
• How human activity affects the ecosystem services karst landforms provide
• Fluvial landforms found in the humid tropics include meanders, braided channels and deltas
• Meanders feature a sinuous channel, a river cliff and a point bar
• Braided channels feature mid-channel bars
• Deltas feature a delta plain, a delta front and a prodelta
• The role geomorphic processes play in forming fluvial landforms, including how waves and tides remove and redistribute sediment to build deltas
• The factors that shape how fluvial landforms form
• The ecosystem services that deltas provide
• How human activity affects the ecosystem services deltas provide
