7.3 Geographical Processes shaping the coastal environment

1) hydraulic action, corrasion and corrosion
2) wave refraction is when energy is concentrated around headlands and more dispersed along beaches located in bays
3) converging waves due to refraction on headland, wave energy concentrated, wave energy difused,
4) the most common erosional landforms found along the coastline are in Victoria called the famous Australian the twelve Apostles
5) longshore drift, deposition and erosion
7) once the material is eroded away by the wind and waves it is transported to other places to be deposited.
8) the most common depositional landforms found along the coastline are beaches and sand dunes
9) coastal dunes are formed by the action of the wind. once sand is deposited on the beach it is then subject to wind transportation. the wind blows the sand landward, which is then trapped by low-lying vegetation like coastal spinifex.
10) waves usually approach the coast at an angle. Once the waves break they start to lose their energy. as the swash travels up the beach it slows until the force of gravity causes it to travel directly back towards the ocean. the water will then be hit by the next wave and the process begins again. sand is transported along the beach by this process
