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 ...
Following the volcanic activity, a basin formed in the northeast, with deposition in a brackish lake—producing the siltstones and chert of Tung Ping Chau, which have been dated from the early Paleogene period. It is also home to some spectacular cliffs and wave-cut platforms. Landforms such as these are very rarely found in the rest of Hong Kong.
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 ]
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]
The wave caused significant damage to Dyess Army Field and Freeflight International Airport. Kwajalein Atoll -- colloquially referred to as "Kwaj" by residents -- is a ring of islands in the ...
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 Avila Beach and San Simeon piers were already closed due to existing damage and sustained a new round of nature’s wrath. Large waves hammer the Avila Beach Pier on Thursday, Dec. 29, 2023.
