  skos:definition """The ocean floor from the shore of a continent to the abyssal plain.  The
continent margin is the zone separating the continents from the deep-sea
bottom, usually subdivided into the continental shelf, slope, and rise.  
They are two basic types of continental margins: passive, or Atlantic, margins
and active, or Pacific, margins.  Passive margins have little seismic or
volcanic activity and form when continents are rifted apart, creating a new
ocean basin between them.  Active margins are tectonically active and are most
often associated with plate convergence and subduction."""@en ;
