  2. Wave-cut platform - Wikipedia

    en.wikipedia.org/wiki/Wave-cut_platform

    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 ...

  3. Longshore drift - Wikipedia

    en.wikipedia.org/wiki/Longshore_drift

    Spits are formed when longshore drift travels past a point (e.g. river mouth or re-entrant) where the dominant drift direction and shoreline do not veer in the same direction. [6] As well as dominant drift direction, spits are affected by the strength of wave-driven current, wave angle and the height of incoming waves. [7]

  4. Terrace (geology) - Wikipedia

    en.wikipedia.org/wiki/Terrace_(geology)

    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 ...

  5. River terraces (tectonic–climatic interaction) - Wikipedia

    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.

  6. Raised beach - Wikipedia

    en.wikipedia.org/wiki/Raised_beach

    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]

  7. Southerndown Coast - Wikipedia

    en.wikipedia.org/wiki/Southerndown_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.

  9. Cliffed coast - Wikipedia

    en.wikipedia.org/wiki/Cliffed_coast

    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] When the arch collapses as the coastline ...
