This material comes from several different sources and is highly variable in composition depending on proximity to a continent water depth ocean currents.
Thickest sediments on ocean floor.
Examine the data set that illustrates the thicknesses of sediments on the ocean floor.
On the seafloor sediments are thinnest near spreading centers young seafloor and thicker away from the ridge where the seafloor is older and has more time to accumulate.
The crust overlies the solidified and uppermost layer of the mantle the crust and the solid mantle layer together constitute oceanic lithosphere.
Also much thickest near continents.
The ocean basin floor is everywhere covered by sediments of different types and origins.
Sediment thickness in the oceans averages about 450 metres 1 500 feet.
Sediments are also much thickest near continents.
At the edge of the ocean basins where the oceanic crust is the oldest.
The thickest accumulation of sediment on the ocean floor is at the continental slopes and rises.
The only exception are the crests of the spreading centres where new ocean floor has not existed long enough to accumulate a sediment cover.
18 3 sea floor sediments except within a few kilometres of a ridge crest where the volcanic rock is still relatively young most parts of the sea floor are covered in sediments.
Sediment thickness increases away from mid ocean ridges in proportion to the amount of time that has elapsed since that particular area of seafloor was created and moved laterally away from the spreading center cooled and subsided figure 6 12.
It relies on sea floor sediments to.
Sediments on the ocean floor are thickest.

Skeletal material from small plants and animals is transported to the seafloor in fecal pellets.
Sediment thickness data were compiled from three principle sources.
Oceanic crust is the uppermost layer of the oceanic portion of a tectonic plate it is composed of the upper oceanic crust with pillow lavas and a dike complex and the lower oceanic crust composed of troctolite gabbro and ultramafic cumulates.
Ocean basin ocean basin deep sea sediments.
Ii ocean drilling results both from the ocean drilling program odp and the deep sea drilling.
Thickness of sediment on the ocean floor 14 in addition to studying the oceanic crust scientists also study the sediments sand mud clay etc that have been deposited on top of the oceanic crust.
Seafloor geomorphology as benthic habitat 2012.
The study of how the ocean atmosphere and land have interacted to produce changes in ocean chemistry circulation biology and climate.
Away from the ridge where the sea floor is older and has more time to accumulate.
