    Continental Margins

    Continental margins border continental landmasses are submarine geographic regions located between the shoreline and deep ocean. They are the submerged edge of continents. Continental margins include subregions and submarine geographic features:

    • continental shelf
    • continental slope
    • continental rise
    • submarine canyons

    The width of continental margins varies: "passive margins" tend to be wider (like the East Coast) compared with " active margins" which tend to narrower (like the West Coast).

    Continental margins are influenced by "continental processes" including tectonic uplift and subsidence, and erosion and deposition.
