Marine erosion processes: hydraulic action, wave quarrying, corrasion/abrasion, cavitation, solution, attrition
Waves erode coastlines through six distinct processes. Each process removes or wears down rock in a different way, from the sheer force of water to chemical dissolving.
Real World
The rapid collapse of sections of the Holderness cliffs in East Yorkshire — retreating at an average 2 metres per year, the fastest rate in Europe — is driven largely by hydraulic action and corrasion attacking soft boulder clay, with cavitation accelerating erosion at the cliff base during storms.
Exam Focus
Name and define the specific erosion process for every mark available — never list processes without explaining the mechanism.
