Coastal erosion - Wikipedia
On non-rocky coasts, coastal erosion results in rock formations in areas where the coastline contains rock layers or fracture zones with varying resistance to erosion. Softer areas become eroded much faster than harder ones, which typically result in landforms such as tunnels, bridges, columns, and pillars.

Aug 18, 2022 · Cliffs along California’s northernmost coast have been eroding faster than the more populated bluffs of Southern California — one of many conclusions highlighted in a new map and study that...
Coastal Erosion | U.S. Climate Resilience Toolkit
Coastal erosion is the process by which local sea level rise, strong wave action, and coastal flooding wear down or carry away rocks, soils, and/or sands along the coast.
What is coastal erosion? - Internet Geography
There are four main processes of coastal erosion. These are corrasion, abrasion, hydraulic action and attrition. Corrasion is when destructive waves pick up beach material (e.g. pebbles) and hurl them at the base of a cliff. Over time this can loosen cliff material forming a wave-cut notch.

Coastal Cliffs - Coastal Processes Group
Seacliff erosion threatens coastal structures, public property, recreational resources, public safety, and major transportation corridors along the California coast . To combat these problems, seawalls are increasingly used to prevent erosion.
