Sea floor structure. Benthos is the community of organisms which live on in or near the seabed the area known as the benthic zone. Terrigenous sediment is derived from land and usually deposited on the continental shelf continental rise and abyssal plain. 2020 for phase one of the underwater data center experimentation. This community lives in or near marine sedimentary environments from tidal pools along the foreshore out to the continental shelf and then down to the abyssal depths the benthic zone is the ecological region on in and immediately above the seabed including the sediment surface.

Mountains plains channels canyons exposed rocks and sediment covered areas. The lack of weathering and erosion in most areas however allows geological processes to be seen more clearly on. The mid atlantic ridge for instance separates the north american plate from the eurasian plate and the south american plate from the african plate the east pacific rise is a mid ocean ridge that runs through the eastern pacific ocean and separates the pacific plate from the north american. The following features are shown at example depths to scale though each feature has a considerable range at which it may occur.

It is further contoured by strong currents along the continental rise. There are three kinds of sea floor sediment. Other articles where ocean floor is discussed. Recent examples on the web floating near the shipping lanes of the santa barbara channel the buoy is attached to an underwater microphone known as a hydrophone positioned 200 meters deep on the seafloor.

The ocean floor has the same general character as the land areas of the world. Seafloor definition is seabed. Continental shelf 300 feet continental slope 300 10 000 feet abyssal plain 10 000 feet abyssal hill 3 000 feet up from the abyssal plain seamount 6 000 feet. Seafloor spreading occurs along mid ocean ridges large mountain ranges rising from the ocean floor.
