Shore platform

...Wave-cut platforms are often formed in the intertidal zone, and it has been pointed out that their origin is due to differences in weathering processes due to differences in height near the sea surface, in addition to the erosive action of waves. In particular, it is said that the style and speed of weathering and erosion differ depending on the degree of alternation between wet and dry due to the repeated ebb and flow of the tides. In addition to wave-cut platforms in the intertidal zone, there are similar topographical features such as storm benches developed by storm waves above high tide level, and high-tide benches and low-tide benches developed near the high-tide and low-tide lines. These are often collectively referred to as benches or shore platforms. At the seaward end of wave-cut platforms, there is a small cliff with a height of several meters, and offshore, a topographical feature called a sea-cut platform develops. ...

…波食棚は潮間帯に形成されることが多いが，その成因は，波の浸食作用のほかに，海面付近での高度差による風化営力の差に基づくことが指摘され，とくに潮汐の干満の繰返しによる乾湿の交代をどのくらい受けているかによって，風化･浸食の様式と速さが異なるといわれている。また潮間帯の波食棚のほかに，高潮位より高い位置に暴風波によって発達するストーム･ベンチや，高潮線や低潮線付近に発達する高潮線ベンチ，低潮線ベンチなどの類似の地形が存在するので，これらを一括して，単にベンチまたはショア･プラットフォームshore platformとよぶことも多い。波食棚の海側末端には比高数mの小崖があり，その沖合には海食台とよばれる地形が発達する。…
