Lithology: Type of rock and its characteristics have different resistance to erosion. Rocks that are well jointed erode quickly as the sea can penetrate along lines of weakness. Variation in rates is called differential erosion.
Sea depth: Steeply shleving sea beds at the coast creates higher and steeper waves, meaning the have more energy and therefore potential to erode.
Fetch: The further a wave has travelled, the more energy it has collected meaning it has higher eroding potential.
Coastal Configuration: Headlands attract wave energy through refraction.
Beach Presence: Beaches absorb wave energy and provide protection against erosion. Shingle beaches dissipate energy through friction and percolation.
Human Activity: People may remove protective materials from beaches leading to more erosion or can reduce it by building sea defences.
