The Ocean Floor Is Made Of

It is composed of several layers not including the overlying sediment.

The ocean floor is made of.

The ocean floor is made up of various landscapes including mountains valleys and plains. Oceanic plates are continuously forged at mid ocean ridges an undersea mountain chain created where the edges of two plates are separating. The lack of weathering and erosion in most areas however allows geological processes to be seen more clearly on the seafloor than. 1 terrigenous describes the sediment derived from the materials eroded by rain rivers glaciers and that which is blown into the ocean by the wind such as volcanic ash.

These vary from oozes made of carbonate from foraminiferal and calcareous phytoplankton and some silica that has settled through the water column. The deepest segments of the ocean floor are found covered by clay and the skeletal remains of microplankton. Then at what bearing are you proceeding is the main issue. As compared to freshwater saline ocean water is and therefore provides support to floating objects.

Most of the igneous rocks within oceanic abyssal plains are denser. The ocean floor has the same general character as the land areas of the world. So even the centre is not reached. These underwater surfaces of the ocean floor are located from the shallowest part of the ocean to its deepest part.

The part of the ocean floor that is under deep water beyond the continent margin and that is composed of oceanic crust and a thin layer of sediment. There are four basic types of sediment of the sea floor. Plate tectonics and the ocean floor bathymetry the shape of the ocean floor is largely a result of a process called plate tectonics. The outer rocky layer of the earth includes about a dozen large sections called tectonic plates that are arranged like a spherical jig saw puzzle floating on top of the earth s hot flowing mantle.

2 biogenous material is the sediment made up of the hard parts of sea animals that accumulate on the bottom of the ocean. In the deepest parts of the. Most of the seafloor is covered by sediments that average 350 m thick. Bottom of the ocean floor is possible only if your starting point has ocean at its anti pod this too is imaginary.

Oceanic crust is about 6 km 4 miles thick. It extends from the shore to a depth of about 600 feet and has a gentle slope. Shallow parts of the ocean floor that are made of continental crust and a thick wedge of sediment. If the bearing is to the centre of the earth you are through the core of the earth almost at the centre.

If you could sit right under a ridge you would see rocks from the earth s mantle the hot layer underlying the crust melting and percolating up toward the seam between the two plates.
