Some of the energy is reflected back from various layers to the surface, making it possible to determine the nature of the layers. A sequence of igneous rocks representing a fragment of oceanic lithosphere; composed of peridotite overlain successively by gabbro, sheeted basalt dikes, and pillow lava. The area separating the part of a continent above sea level from the deep seafloor. The very gently sloping part of the continental margin between the shoreline and the continental slope. The relatively steeply inclined part of the continental margin between the continental shelf and the continental rise or between the continental shelf and an oceanic trench. The gently sloping part of the continental margin between the continental slope and the abyssal plain. A sediment‐water mixture, denser than normal seawater, that flows downslope to the deep seafloor. A coneshaped sedimentary deposit that accumulates on the continental slope and rise. A steep‐walled canyon best developed on the continental slope, but some extend well up onto the continental shelf. A continental margin with volcanism and seismicity at the leading edge of a continental plate where oceanic lithosphere is subducted. A continental margin within a tectonic plate as in the East Coast of North America, where little seismic activity and no volcanism occur; characterized by a broad continental shelf and a continental slope and rise. Vast flat area on the seafloor adjacent to the continental rise of a passive continental margin A long, narrow feature restricted to active continental margins and along which subduction occurs. A mostly submarine mountain system composed of basalt found in all ocean basins. A crack or fissure in the seafloor through which superheated water issues. A type of submarine hydrothermal vent that emits a black plume of hot water colored by dissolved minerals. A submarine volcanic mountain rising at least 1 km above the seafloor. A flat‐topped seamount of volcanic origin rising more than 1 km above the seafloor. A ridge or broad area rising above the seafloor that lacks seismic activity. Brown or red deep‐sea sediment composed of clay‐sized particles. Deep‐sea sediment composed mostly of shells of marine animals and plants. A mound‐like, waveresistant structure composed of the skeletons of organisms. An area extending 371 km seaward from the coast of the United States and its possessions in which the United States claims rights to all resources.
