Deep Sea Floor Surface Area

But with the constantly decreasing supply on land some mining specialists see oceanic mining as the destined future.

Deep sea floor surface area.

Basalt the once molten rock that makes up most new oceanic crust is a fairly magnetic substance and scientists began using magnetometers to measure the magnetism of the ocean floor in the 1950s what they discovered was that the magnetism of the ocean floor around. A andesitic mountains b basaltic nodules c deep trenches. The deep ocean floor comprises of the earth s surface area. Benthos is the community of organisms which live on in or near the seabed the area known as the benthic zone.

The deep sea or deep layer is the lowest layer in the ocean existing below the thermocline and above the seabed at a depth of 1000 fathoms 1800 m or more. The ocean floor is sometimes called the final frontier of the modern era. They are among the flattest smoothest and least explored regions on earth. An ocean is a body of water that composes much of a planet s hydrosphere.

The magnetism of mid ocean ridges helped scientists first identify the process of seafloor spreading in the early 20th century. A about 3 b more than half c over 70 d very little. The phrases the ocean or the sea used without specification refer to the interconnected body of salt water covering the. 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.

The ocean surface is vast and hides an entire world underneath it. The ocean is a common aquatic biome consisting predominantly of water oceans are the largest biome by area covering anywhere around 25 33 of the surface area of the overworld when factoring in all of its variants and consist of a deep body of water with the surface at an altitude of y 63 by default which is counted as the sea level of the world. 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. We know very little about the vast expanse of our oceans.

Seamounts are a possible future source of economically important metals. On earth an ocean is one of the major conventional divisions of the world ocean these are in descending order by area the pacific atlantic indian southern antarctic and arctic oceans. Little or no light penetrates this part of the ocean and most of the organisms that live there rely for subsistence on falling organic matter produced in the photic zone for this reason scientists once assumed that life would be sparse. The following features are shown at example depths to scale though each feature has a considerable range at which it may occur.

When two plate margins converge and one is pulled down into the mantle are formed. Even though the ocean makes up 70 of earth s surface area technological challenges have severely limited the extent of deep sea mining.
