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 areas of flat rock.
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.
Truncated spur – Ridge that descends towards a valley floor or coastline that is cut short; Tor – Large, free-standing rock outcrop on a gentle hill summit; Valley – Low area between hills, often with a river running through it; Wave-cut platform – Narrow flat area created by erosion; Wind gap – Topographic gap made by a former waterway
Coastal geography is the study of the constantly changing region between the ocean and the land, ... Wave-cut platform; Longshore drift. Deposition (sediment)
Typical sequence of erosional marine terraces. 1) low tide cliff/ramp with deposition, 2) modern shore (wave-cut/abrasion-) platform, 3) notch/inner edge, modern shoreline angle, 4) modern sea cliff, 5) old shore (wave-cut/abrasion-) platform, 6) paleo-shoreline angle, 7) paleo-sea cliff, 8) terrace cover deposits/marine deposits, colluvium, 9) alluvial fan, 10) decayed and covered sea cliff ...
On a rocky cliffed coast made up of material which is relatively resistant to erosion such as sandstone, limestone or granite, a flat rocky wave-cut platform or abrasion platform is formed in front of the cliff. It represents the foot of the cliff preserved at and below the level of water table.
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 ...
