Although it is underwater, a continental shelf is part of the continental margin, not the deep-ocean basin. Changes in sea level affect the continental shelves.
Continents are outlined in most places by a zone of shallow water where the ocean covers the end of the continent.
The part of the continent that is covered
by water is called the
continental shelf
.
The shelf usually slopes gently from the shoreline and drops about 0.12 m every 100 m.
The average depth of the water covering a continental shelf is about 60 m.
Although
it is underwater
, a continental shelf is
part of the continental margin
, not the deep-ocean basin.
Changes in sea level affect the continental shelves.
