A coast – also called the coastline, shoreline, or seashore – is the land next to the sea or the line that forms the boundary between the land and the ocean or a lake. [1] [2] Coasts are influenced by the topography of the surrounding landscape, as well as by water induced erosion, such as waves.
Collapsed Ordovician limestone bank showing coastal erosion.NW Osmussaar, Estonia.. Coastal geography is the study of the constantly changing region between the ocean and the land, incorporating both the physical geography (i.e. coastal geomorphology, climatology and oceanography) and the human geography (sociology and history) of the coast.
A marine coastal ecosystem is a marine ecosystem which occurs where the land meets the ocean. Worldwide there is about 620,000 kilometres (390,000 mi) of coastline. Coastal habitats extend to the margins of the continental shelves, occupying about 7 percent of the ocean surface area.
In Greece, according to the L. 2971/01, the foreshore zone is defined as the area of the coast that might be reached by the maximum climbing of the waves on the coast (maximum wave run-up on the coast) in their maximum capacity (maximum referring to the "usually maximum winter waves" and of course not to exceptional cases, such as tsunamis ...
Definition (marine biology), context, extra terminology [ edit ] In marine biology , the neritic zone , also called coastal waters , the coastal ocean or the sublittoral zone , [ 3 ] refers to that zone of the ocean where sunlight reaches the ocean floor , that is, where the water is never so deep as to take it out of the photic zone .
"This correlation was demonstrated at the low energy clayey tidal flats of Bohai Bay (China), the moderate environment of the Jiangsu coast (China) where the bottom material is silty, and the sandy flats of the high energy coast of The Wash (U.K.)." This research shows conclusive evidence for the null point theory existing on tidal flats with ...
These cracks then gradually get larger and turn into caves. If a cave wears through a headland, an arch forms. Further erosion causes the arch to collapse, leaving the pillar of hard rock standing away from the coast, the stack. Eventually, erosion will cause the stack to collapse, leaving a stump.
The Indonesian Barrier Islands lie off the western coast of Sumatra. From north to south along this coast they include Simeulue, the Banyak Islands (chiefly Tuangku and Bangkaru), Nias, the Batu Islands (notably Pini, Tanahmasa and Tanahbala), the Mentawai Islands (mainly Siberut, Sipura, North Pagai and South Pagai Islands) and Enggano Island.
