GCSE Unit 2 : Coastal Landscapes Geography is easy

WebbCoastal processes include wave action (erosion, transport and deposition), wind action, littoral drift, and subaerial processes (weathering, eg salt crystal growth, and mass movement, eg slumping). Coastal features include erosional landforms such as cliffs and wave-cut platforms, as well as depositional landforms such as spits and bars. WebbIn the thermodenudation process, thermal energy thaws the permafrost during the summer, leading to slumping of the thawed bluffs via gravitational forces. The slumped materials … WebbSlumping occurs when material moves along a curved path. The technical term is ‘rotation’ so slumping is also known as ‘rotational slip’ or ‘rotational slump’. In the photograph the path of the slump is highlighted by the red line. It occurs mainly in soft and uniform rocks such as silts and clays, and can be triggered by heavy rain. pop of america 2021
