The gently sloping submerged portion of the continental margin extending from the shoreline to the continental slope.
gently sloping, shallow-water platform extending from the coast to the shelf break, where there is a steep descent to the ocean floor
the relatively shallow flat portion of the sea floor extending from the shoreline to the shelf break, where the sea floor abruptly slopes downward.
the zone of the sea floor that stretches from the continent to the continental slope where there is a steep slope to deep water.
A flat, projecting extension of land submerged beneath a shallow sea.
Edge of a continent which lies under seas less than 200 metres deep.
The sea floor adjoining a large land mass as distinct from the deeper waters of the wider ocean bed.
the relatively shallow portion of the sea floor that adjoins and surrounds most parts of the continents.
The submerged, relatively flat and gently sloping part of a continent extending from shore to about 100 fathom
submerged shelf of land bordering most continents.
The relatively shallow region between the land and the deep ocean subject to deposition of terrestrial products.
The oceanic margin of the continents, characterized by a relatively flat bottom. Generally defined as the benthic area out to 200m depth.
The zone around the continents extending from the low-water mark seaward, typically ending in steep slope to the depths of the ocean floor.
a shallow submarine plain bordering a continent and typically ending in a steep slope to the deep ocean.
The edge of a continental mass that lies under the sea in comparatively shallow water (up to a water depth of about 240 metres (800 feet).
The offshore seabed down to a depth of about 200m.
A submerged part of the land mass which gently slopes from shore to relatively shallow depths of 655 feet (200 meters).
The shallow bottom just offshore of most continents between water's edge and a sharp drop-off where the bottom plunges steeply [more
Section of the seabed from the shore to the edge of the continental slope - commonly taken to be the 200 m depth contour (isobath).
An area of continental crust covered by the sea.
The area seaward from the ocean shore to the distance when the ocean depth is 200 meters, or where the ocean floor slopes more steeply to the deep ocean floor. The area beyond the state's jurisdiction is the OUTER Continental Shelf.
The submerged margin of a continental mass extending from the shore to the first prominent break in slope.
n. The part of the continental margin from the coastal shore to the continental slope; usually extending to a depth of about 200 meters and with a very slight slope, roughly 0.1 degrees; includes conetinental and oceanic sediments down to the ocean floor.
The part of the sea floor that gradually descends from the coastline to depths of about 600 feet (182 meters); from there, the bottom drops down sharply, forming the continental slope to the great depths of the ocean.
The portion of the sea bottom that slopes gradually from the edge of a continent. Usually defined as areas where water is less than 200 meters or 600 feet deep.
The zone around the continents extending from the low-water mark seaward to where there is a marked increase in slope to greater depths.
The region of the oceanic bottom that extends outward from the shoreline with an average slope of less than 1:100, to a line where the gradient begins to exceed 1:40.
an old, wave-cut terrace gently sloping seaward
An area of relatively shallow seabed which lies between the shore of a continent and the deeper water of the ocean.
A gently sloping area extending from the low-water line to the depth of a marked increase in slope around the margin of a continent or island
Part of the continental margin between the coast and the continental slope.
Area of sea floor adjacent to a continent, sloping gently to a depth of about 655 feet (200 m); beyond the shelf edge, the sea floor drops steeply (via the continental slope) to the ocean bottom.
The continental shelf is the part of the ocean floor next to each of the continents. The sea floor slopes gradually from the continent to a depth of about 100 metres. Beyond the continental shelf the sea floor drops steeply
The submerged shelf of land that slopes gradually from the exposed edge of a continent to where the drop-off to the deep seafloor begins.
Shallow submerged margin of the continents that lies between the edge of the shoreline and the continental slope. This nearly level area of the continental crust has surface layers composed of sediment or sedimentary rock.
The offshore area of a continent in shallow sea [LCOTE
The continental shelf is the extended perimeter of each continent, which is covered during interglacial periods such as the current epoch by relatively shallow seas (known as shelf seas) and gulfs. The shelf usually ends at a point of increasing slope (called the shelf break). The sea floor below the break is the continental slope.
