They vary in size from relatively minor features of the continental margin to vast structural divisions of the deep ocean.

Floor of major ocean basin.

More modern sources e g floyd 1991 regard the ocean basins more as basaltic plains than as sedimentary depositories since most sedimentation occurs on the continental shelves. Which of the following are commonly found along ocean to ocean convergent zones. Older references e g littlehales 1930 consider the oceanic basins to be the complement to the continents with erosion dominating the latter and the sediments so derived ending up in the ocean basins. In fact it will.

The largest ocean basins are 3 to 5 kilometers 2 to 3 miles deep and stretch from the outer margins of the continents to the mid ocean ridges. On average oceanic crust is only 6 to 7km thick compared to 35 to 40km for con tinental crust. Ocean basin ocean basin deep sea sediments. At depths of over 10 000 feet and covering 70 of the ocean floor abyssal plains are the largest habitat on earth.

The ocean basins are characterized not only by lying in deep water the ocean floor averages about 4km below sea level but also by being underlain by a thin layer of crust. It also causes magma to rise up from the mantle of the earth forming crusts. A number of major features of the basins depart. Within the areas of the pacific ocean basin there is a ridge that forms from the gulf of california right down to the west of the southern part of south america.

The crust overlies the solidified and uppermost layer of the mantle the crust and the solid mantle layer together constitute oceanic lithosphere. 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. Together they contain the overwhelming majority of all water on the planet and have an average depth of almost 4 km about 2 5 miles. Ocean basin any of several vast submarine regions that collectively cover nearly three quarters of earth s surface.

All of the above oceanic trenches active earthquake zones island arc systems. It causes a rise of the ocean floor around 2 130 metres. About 70 of the planet s surface is made up of ocean basins which are the regions that are below sea level these areas hold the majority of the planet s water. Continuing your journey across the ocean basin you would descend the steep continental slope to the abyssal plain.

Sediment thickness in the oceans averages about 450 metres 1 500 feet.
