- 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.

| Abstract from DBPedia | A continental margin is the outer edge of continental crust abutting oceanic crust under coastal waters. It is one of the three major zones of the ocean floor, the other two being deep-ocean basins and mid-ocean ridges. The continental margin consists of three different features: the continental rise, the continental slope, and the continental shelf. The continental shelf is the relatively shallow water area found in proximity to continents. Continental margins constitute about 28% of the oceanic area.大陸斜面（たいりくしゃめん、continental slope）は、海底の地形（）の一つで、大陸棚と大洋底（または深海底）の間の急な斜面。ここには海底谷や海底扇状地などが存在する。水深200m〜2440m。 (Source: http://dbpedia.org/resource/Continental_margin) |
