Notes contrast constructive and destructive waves, linking wave characteristics to depositional or erosional landforms and explaining factors that control wave size such as wind strength, duration, water depth and fetch. The document then details core coastal processes—erosion, weathering, transportation, mass movement and deposition—before expanding on erosional methods like corrasion, abrasion, attrition, hydraulic action and corrosion (solution), plus key landforms including caves, arches, stacks, stumps and wave-cut notches and platforms.","AQA Geography GCSE  \n# Coastal Landscapes in the UKDetailed Notes\n\n## Coastal Landscapes\n\nWaves and Sea Levels  \nMost waves form due to the wind blowing across the surface of the sea.The wind pulls the surface(through friction)and creates ripples that increase in height as they travel towards the beach.Thereare two types of waves which have different characteristics:  \nConstructive waves  \n·Strong swash,weak backwash  \n·Low wave height,large wavelength  \n·Low frequency  \n·  Depositional-the waves leavematerial on the beach,and so build upthe material (sand,pebbles,etc)overtime.Powerful&DamagingWaves are closer together(short wavelength)which increases the energy of the wave.  \nDESTRUCTIVE WAVES  \nDestructive waves  \n·  Strong backwash,weak swash  \n·High wave height,small wavelength  \n·High frequency  \n·Erosional-the waves erode thebeach and any rocks and take thematerial away to other locations.Overtime,the beach wears away.  \nwww.pmt.education  \n口回f9PMTEducation  \nThe size of a wave depends on various factors including:  \n-  The strength of the wind  \n-How long the wind has been blowing for  \n-Water depth  \n-The fetch -the distance the waves have travelled from where they originated from  \nThe coastlines which are hit by constructive waves tend to have depositional landforms such assandy beaches.This is because the waves are less powerful and deposit material (sand,pebbles,etc)rather than taking it away from the beach.  \nCoastlines that are hit by destructive waves typically have erosional landforms such as rockyheadlands and landforms,such as tall cliffs and caves.Destructive waves tend to have a longfetch and so are the most powerful waves.These coastlines tend to erode away and retreat.  \n## Coastal Processes and Land Formations\n\nThere are five coastal processes that you need to know for your exam:erosion,weathering,transportation,mass movement and deposition.Each process can produce several coastalfeatures,which can be found all along the UK coastline.  \n### Erosional Processes\n\nErosion is the removal anddestruction of rocks and sand alongthe coastline.There are five differenttypes of erosion,but they tend towork together to break down a rockface in their own ways:  \nThe five erosion processes are:  \n● Corrasion -  Sand andpebbles are picked up by thesea and hurled against thecliffs at high tide,causing thecliffs to be eroded.Theshape,weight and quantity ofsediment picked up,as wellas the wave speed,affectsthe rate of erosion.  \n·Abrasion -This is the process where sediment scrapes and bangs against the base of arockface,and so wear away the face gradually(like sandpaper against a piece of wood).The pieces of rock brush past the rockface,rather than being launched against the rockfacein corrasion.  \nPMTEducation  \n·Attrition -Wave action causes rocks and pebbles to hit against each other,wearingeach other down and so becoming round and eventually smaller.Attrition is an erosiveprocess within the coastal environment,but has little to no effect on erosion of the coastlineitself.  \n·Hydraulic Action -As a wave crashes onto a rock or cliff face,air is forced into crackswithin the rock.The high pressure causes the cracks to force apart and widen when thewave retreats and the air expands.Over time this causes the rock to fracture.  \n·Corrosion(Solution)-The mildly acidic seawater can cause alkaline rock such aslimestone to be eroded.This is similar to chemical weathering(later in these notes)wereacid rain dissolves limestone within the rockface.  \n### Erosional Landforms\n\nCaves.Arches.Stacks &Stumps-This  \nsequence occurs on pinnacle headlands.  \nMarine erosion widens cracks in the base ofthe headland,these get bigger over time andcreate a cave.  \nThe cave widens and deepens due to bothmarine erosion and sub-aerial processes,and eventually a large hole willform throughto the other side of the headland.This isknown as an arch.  \nThe arch continues to widen until it is unable to support itself,the top falls due to its own weightt","cbCaiuOJGIh2nHcZ","https://ap.wps.com/l/cbCaiuOJGIh2nHcZ","pdf",3282851,1,14,"English","en",105,"# Coastal Landscapes\n## Waves and Sea Levels\n## Coastal Processes and Land Formations\n### Erosional Processes\n### Erosional Landforms\n## Transportation","[{\"question\":\"How do constructive and destructive waves differ, and what landforms do they create?\",\"answer\":\"Constructive waves have strong swash and weak backwash, lower wave height and long wavelength, leading to deposition such as sandy beaches.
