How does longshore drift cause erosion
http://geography.learnontheinternet.co.uk/topics/coastal_processes.html WebWhen a wave breaks, the trapped air is compressed which weakens the cliff and causes erosion. Abrasion Bits of rock and sand in waves grind down cliff surfaces like sandpaper. Attrition Waves smash rocks and pebbles on the shore into each other, and they break and become smoother. Solution

WebSpits are eroded by the sea and wind but a constant supply of sediment from longshore drift ensures their continued existence. Events such as storms change the shape of a spit drastically over short periods of time though. During a storm event, erosion exceeds deposition so a lot of material is removed from the spit, changing its shape. WebLongshore drift plays a large role in the evolution of a shoreline, as if there is a slight change of sediment supply, wind direction, or any other coastal influence longshore drift can …

The movement of sand plays a fundamental role in creating and shaping our coastal environment. Driven by waves, longshore drift transports sediment, mainly sand, from New South Wales up the coast to form our beaches and sand islands. Wave action. Wave action determines the shape and state of our beaches and coast.
WebLongshore drift has a very powerful influence on the shape and composition of the coastline.
