Where is ocean flooring sediment inmost?

Sediments can likewise form by the build-up of shells of dead organism and can include mineral and/or fossil. Inmost locations of ocean flooring which is far from land are controlled by abyssal clay which is called “red clay” and includes smaller sized sediments which are brought away by the currents and winds.

Exists sediment on the ocean flooring?

Sea-floor sediments (and sedimentary rocks) can vary in density from a couple of millimetres to a number of 10s of kilometres Near the surface area, the sea-floor sediments stay unconsolidated, however at depths of hundreds to countless metres (depending upon the kind of sediment and other aspects) the sediment ends up being lithified.

Is the ocean flooring soft?

In the inmost parts of the ocean, you’ll discover layers of Earth’s crust comprise the ocean flooring. These inmost layers are comprised of rock and minerals.
