Document Summary
7 continents make up most of most of the surface. Features of the ocean include: deep trenches, submarine mountain ranges. Part of the seafloor have mountains, the largest one form islands (hawaii) Island and seamount chains (seafloor mountains): islands and seamounts that are in long belts. Much of the ocean floor is moderately very deep and has fairly smooth surface-called abysall plains. Some continents continue outwards from the shoreline under shallow sea water forming submerged benches (narrow flat land) called continental shelves. All continents contain large interior regions with topography. Some continents have flat coastal plain while some have mountain around the edges. Deep mountain trenches make up the deeper parts of the ocean. Some ocean trenches follow the edge of the continents, while others are isolated. (located near pacific ocean) Island arcs, curving chains, cross the seafloor. Mid-ocean trenches and there fracture zones encircle much of the globe. Ocean plateus: ocean containing several broad, evaluated regions.
