On a cliffed coast made up of material which is only fairly or even hardly resistant to erosion no wave-cut platform but a beach is formed in front of the sea cliff. If waves carve notches at a narrow point on both sides of a promontory on the rocky cliffed coast, a natural arch may be formed. [4]
Wave-cut platform at Southerndown, South Wales, UK. A wave-cut platform, shore platform, coastal bench, or wave-cut cliff is the narrow flat area often found at the base of a sea cliff or along the shoreline of a lake, bay, or sea that was created by erosion. Wave-cut platforms are often most obvious at low tide when they become visible as huge ...
Holly Lane SSSI (grid reference) is a 0.5 hectare geological Site of Special Scientific Interest near the village of Walton St. Mary, North Somerset, notified in 1990.. This Geological Conservation Review site shows deep subaerial sands and breccias burying a fossil cliff, shoreplatform, wave-cut notch and cave.
[10] [25] The retreat of the sea cliff generates a shore (wave-cut/abrasion-) platform through the process of abrasion. A relative change of the sea level leads to regressions or transgressions and eventually forms another terrace (marine-cut terrace) at a different altitude, while notches in the cliff face indicate short stillstands.

The northern section is the wave-cut platform alongside Ogmore-by-Sea. The southern section, with a short gap, covers both the intertidal areas and the cliffs and grassy cliff-tops of Dunraven Bay, Trwyn y Witch headland and the valleys and shoreline of Cwm Mawr and Cwm Bach. [ 2 ]
Wave-cut notches are caused by the undercutting of overhanging slopes which leads to increased stress on cliff material and a greater probability that the slope material will fall. The fallen debris accumulates at the bottom of the cliff and is eventually removed by waves.
This lemon-dill tuna salad packs plenty of protein and gets a boost of flavor from sumac—a spice used in Middle Eastern, Mediterranean and North African cooking that adds a citrusy touch ...
Wave cut platform; Sea cave such as King's Cave, Isle of Arran; The Scottish Gaelic word machair or machar refers to a fertile low-lying raised beach found on some of the coastlines of Ireland and Scotland (especially the Outer Hebrides). Hudson Bay, in Canada's north, is an example of an emergent coastline. It is still emerging by as much as 1 ...
