However the lowest point in the world ocean is much deeper than the highest point on land.

Structure of ocean floor information.

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. The ocean floor has the same general character as the land areas of the world. Three quarters of the earth consists of ocean water. Like dry land the ocean floor has various features including flat plains sharp mountains and rugged canyons fig.

Known as manganese nodules they are composed of layers of different metals like manganese iron nickel cobalt and copper and they are always found on the surface of the ocean floor. Mountains plains channels canyons exposed rocks and sediment covered areas. Plate tectonics and the ocean floor bathymetry the shape of the ocean floor is largely a result of a process called plate tectonics. If mount everest was placed in the deepest part of the ocean its peak would be covered by over 7000 feet of seawater.

Ocean floor configuration divisions of the ocean floors an oceanic basin is the land surface under an ocean that includes the topography under the water. An ocean is a body of water that composes much of a planet s hydrosphere. The ocean floor is continually being formed and destroyed. The lack of weathering and erosion in most areas however allows geological processes to be seen more clearly on the seafloor than.

Cosmogenous sediments are the remains of space debris such as comets and asteroids made up of silicates and various metals that have impacted the earth. The average depth of the ocean is around 14000 feet which is equal to the statue of liberty stacked one top of itself forty seven times sc 1. This video examines the different types of features in the ocean primarily on the ocean floor. The ocean floor covers more than 70 percent of the planet s surface.

The ocean floors can be divided into four major divisions. All these details are incorporated on underwater topography maps. Science has established that the topography of the ocean floor is similar to the ground topography with features such as valleys mountains and plateaus. Continental margin and oceanic divisions.

This layered structure is called cumulate meaning that the layers which measure up to several metres thick result from the sedimentation of minerals out of the liquid magma.
