MARINE AND COASTALPROCESSES ANDTHEIR EFFECTSGROUP III
Coastal ProcessesCoastal ProcessesCoastal landforms are created by a wide variety of coastal processes, which varydepending on the process, the wave climate, beach morphology, geology, and human activity. Thisresults in the two umbrella processes of erosion and accretion.Erosionis defined as “the group of processes whereby debris or rock material is loosened or dissolved”(Thomas & Goudie, 2000), whilstAccretion is “the gradual increase in the area of land as a result of sedimentation” (Thomas & Goudie,2000). Both processes cover a number of sub-processes, some of which cause both erosion andaccretion.Abrasionoccurs when windblown sand or water-borne shingle is thrown against cliffs. It is probably themost effective form of erosion on rocky shores. Waves can cause abrasion on their own, but only on softformations such as clay and shale.Attrition is the process of breaking down material lost from cliffs and rocky shores by abrasion.Corrosion / solution mainly takes place on limestone cliffs, such as those around Dover or Beachy Head,
