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 ...
A marine terrace represents the former shoreline of a sea or ocean. It can be formed by marine abrasion or erosion of materials comprising the shoreline (marine-cut terraces or wave-cut platforms); the accumulations of sediments in the shallow-water to slightly emerged coastal environments (marine-built terraces or raised beach); or the bioconstruction by coral reefs and accumulation of reef ...
Subsequent wave erosion along uplifted portions of the coastline produces an inset wave cut platform and terrace riser below the abandoned marine terrace surface that formed initially at sea level. Uplift can therefore lead to a sequence of marine terraces at a few distinct elevations along the coast.
The SSSI is in two parts. 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.

Furthermore, shore platforms are formed by denudation and marine-built terraces arise from accumulations of materials removed by shore erosion. [2] Thus, a marine terrace can be formed by both erosion and accumulation. However, there is an ongoing debate about the roles of wave erosion and weathering in the formation of shore platforms. [10]
On the cliff west of the village is the Perenco "nodding donkey" oil pump which has been pumping continually since the late 1950s, making it the oldest working oil pump in the UK. The well currently yields around 65 barrels per day (10.3 m 3 /d) from the Middle Jurassic strata that lie around 1,150 feet (350 m) below the cliff.
Also, they include benches in the form of narrow strath terraces (st), fill terraces (ft), and cut terraces (ct) underlain by fluvial sediments. In geomorphology , geography and geology , a bench or benchland is a long, relatively narrow strip of relatively level or gently inclined land bounded by distinctly steeper slopes above and below it.
It represents the foot of the cliff preserved at and below the level of water table. If there is a tectonic uplift of the coast, these abrasion platforms can be raised to form coastal terraces, from which the amount of uplift can be calculated from their elevation relative to the sea level, taking into account any eustatic sea level changes.
