Cuspate foreland – Geographical features found on coastlines and lakeshores; Cut bank – Outside bank of a water channel, which is continually undergoing erosion; Dale – Low area between hills, often with a river running through it; Defile – Narrow pass or gorge between mountains or hills; Dell – Small secluded hollow
Coastal erosion is the loss or displacement of land, or the long-term removal of sediment and rocks along the coastline due to the action of waves, currents, tides, wind-driven water, waterborne ice, or other impacts of storms.
Wave-like texture was produced by coastal erosion. In coastal areas in which the land surface dips at a relatively steep angle below the water table, the continuous action of marine waves on the coastline, known as abrasion, may create a steep declivity known as a cliff, the slope angle of which depends on a variety of factors including the ...
A new study pinpoints erosion hot spots along the entire California coast — and found that cliffs in Northern California are disappearing the fastest.
Erosion is just starting to the west, where the sea has again broken through the Portland limestone barrier at Stair Hole. The concordant coast may take one of two landform types. The Dalmatian type, named from Dalmatia on the Adriatic Sea, features long offshore islands and coastal inlets that are parallel to the coastline. The Adriatic Sea ...

Without the constant presence of water, stacks also form when a natural arch collapses under gravity, due to sub-aerial processes like wind erosion. Erosion causes the arch to collapse, leaving the pillar of hard rock standing away from the coast—the stack. Eventually, erosion will cause the stack to collapse, leaving a stump.
Valley or stream erosion occurs with continued water flow along a linear feature. The erosion is both downward, deepening the valley, and headward, extending the valley into the hillside, creating head cuts and steep banks. In the earliest stage of stream erosion, the erosive activity is dominantly vertical, the valleys have a typical V-shaped ...
